      1.GridView简单代码分页排序:

      1.AllowSorting设为True,aspx代码中是AllowSorting="True";

      2.默认1页10条,如果要修改每页条数,修改PageSize即可,在aspx代码中是PageSize="12"。

      3.默认的是单向排序的,右击GridView弹出“属性”,选择AllowSorting为True即可。

      4.添加代码:

          protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)

          {

              GridView1.PageIndex = e.NewPageIndex;

              Bind();

          }

      2.GridView选中,编辑,取消,删除:

                  + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='"

                  + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',字段3='"

                  + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where id='"

                  + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";

              sqlcom=new SqlCommand(sqlstr,sqlcon);

              sqlcon.Open();

              sqlcom.ExecuteNonQuery();

              sqlcon.Close();

              GridView1.EditIndex = -1;

              bind();

          }

      //取消

          protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

          {

              GridView1.EditIndex = -1;

              bind();

          }

      //绑定

          public void bind()

          {

              string sqlstr = "select * from 表";

              sqlcon = new SqlConnection(strCon);

              SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

              DataSet myds = new DataSet();

              sqlcon.Open();

              myda.Fill(myds, "表");

              GridView1.DataSource = myds;

              GridView1.DataKeyNames = new string[] { "id" };//主键

              GridView1.DataBind();

              sqlcon.Close();

          }

      }

       

      前台主要代码:

                                  ... ...

      <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4"

                              ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

      3.GridView正反双向排序:

      后台代码:

      using System;

      using System.Data;

      using System.Configuration;

      using System.Collections;

      using System.Web;

      using System.Web.UI.HtmlControls;

      using System.Data.SqlClient;

      public partial class Default3 : System.Web.UI.Page

      {    SqlConnection sqlcon;

          string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=";

          protected void Page_Load(object sender, EventArgs e)

          {

              if (!IsPostBack)

              {

                  ViewState["SortOrder"] = "身份证号码";

                  ViewState["OrderDire"] = "ASC";

                  bind();

              }

          }

          protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)

          {

              string sPage = e.SortExpression;

              if (ViewState["SortOrder"].ToString() == sPage)

              {

                  if (ViewState["OrderDire"].ToString() == "Desc")

                      ViewState["OrderDire"] = "ASC";

                  else

                      ViewState["OrderDire"] = "Desc";

              }

              else

              {

                  ViewState["SortOrder"] = e.SortExpression;

              }

              bind();

          }

          public void bind()

          {

             

              string sqlstr = "select top 5 * from 飞狐工作室";

              sqlcon = new SqlConnection(strCon);

              SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

              DataSet myds = new DataSet();

              sqlcon.Open();

              myda.Fill(myds, "飞狐工作室");

              DataView view = myds.Tables["飞狐工作室"].DefaultView;

              string sort = (string)ViewState["SortOrder"] + " " + (string)ViewState["OrderDire"];

              GridView1.DataSource = view;

              GridView1.DataBind();

              sqlcon.Close();

          }

      }

      前台主要代码:

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

                      }

                  }

                  sqlcon.Close();

              }

          }

          public SqlDataReader ddlbind()

          {

              string sqlstr = "select distinct 员工性别 from 飞狐工作室";

      6.鼠标移到GridView某一行时改变该行的背景色方法一:

      做法:

      双击GridView的OnRowDataBound事件;

      在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

      protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

          {

          //首先判断是否是数据行

                  if (e.Row.RowType == DataControlRowType.DataRow)

                  {

                      //当鼠标停留时更改背景色

                      e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");

                      //当鼠标移开时还原背景色

                      e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

                  }

          }

      前台代码:

      <html xmlns="http://www.1click-soft.com/tfgjylgw/1999/xhtml" >

      <head runat="server">

          <title>实现鼠标划过改变GridView的行背景色清清月儿http://www.1click-soft.com/tfgjylgw/21aspnet </title>

      </head>

      <body>

          <form id="form1" runat="server">

          <div>

              <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"

                  DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                  <Columns>

                      <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />

                      <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" SortExpression="家庭住址" />

                      <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                  </Columns>

                  <FooterStyle BackColor="White" ForeColor="#000066" />

                  <RowStyle ForeColor="#000066" />

                  <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                  <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                  <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

              </asp:GridView>

              <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"

                  SelectCommand="SELECT top 5 [身份证号码], [姓名], [员工性别], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

         

          </div>

          </form>

      </body>

      </html>

       

      7.鼠标移到GridView某一行时改变该行的背景色方法二:

      做法:和上面的一样就是代码不同

      protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

          {

              //如果是绑定数据行

              if (e.Row.RowType == DataControlRowType.DataRow)

              {

                  //鼠标经过时,行背景色变

                  e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");

                  //鼠标移出时,行背景色变

                  e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

              }

          }

      8.GridView实现删除时弹出确认对话框:

      实现方法:

      双击GridView的OnRowDataBound事件;

      在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

          protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

          {

              //如果是绑定数据行

              if (e.Row.RowType == DataControlRowType.DataRow)

              {

                   if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)

                  {

                      ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除:/"" + e.Row.Cells[1].Text + "/"吗?')");

                  }

              }

          }

      9.GridView实现自动编号:

      实现方法:

      双击GridView的OnRowDataBound事件;

      在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示:

          protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

          {

              if (e.Row.RowIndex != -1)

              {

                  int id = e.Row.RowIndex + 1;

                  e.Row.Cells[0].Text = id.ToString();

              }

          }

       

      注意这时最好把前台的第一列的表头该为“编号”,因为以前的第一列被“吃掉”了。

      <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                              OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                  <asp:BoundField DataField="姓名" HeaderText="用户姓名" />

                                  <asp:BoundField DataField="员工性别" HeaderText="性别" />

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />

                                  <asp:CommandField HeaderText="选择" ShowSelectButton="True" />

                                  <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                  <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

      10.GridView实现自定义时间货币等字符串格式:

      解决方法:

      在asp.NET 2.0中,如果要在绑定列中显示比如日期格式等,如果用下面的方法是显示不了的

      <asp :BoundField DataField="CreationDate"

      DataFormatString="{0:M-dd-yyyy}"

      HeaderText="CreationDate" />

      主要是由于htmlencode属性默认设置为true,已防止XSS攻击,安全起见而用的,所以,可以有以下两种方法解决

      1、

      <asp :GridView ID="GridView1" runat="server">

      <columns>

      <asp :BoundField DataField="CreationDate"

      DataFormatString="{0:M-dd-yyyy}"

      HtmlEncode="false"

      HeaderText="CreationDate" />

      </columns>

      </asp>

      将htmlencode设置为false即可

      另外的解决方法为,使用模版列

      <asp :GridView ID="GridView3" runat="server" >

      <columns>

      <asp :TemplateField HeaderText="CreationDate" >

      <edititemtemplate>

      <asp :Label ID="Label1" runat="server"

      Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>

      </asp>

      </edititemtemplate>

      <itemtemplate>

      <asp :Label ID="Label1" runat="server"

      Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>

      </asp>

      </itemtemplate>

      </asp>

      </columns>

      </asp>

      前台代码:

      <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"

                  DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

                  <Columns>

                      <asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />

                      <asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />

                      <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                      <asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />

                      <asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />

                  </Columns>

                  <FooterStyle BackColor="White" ForeColor="#000066" />

                  <RowStyle ForeColor="#000066" />

                  <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                  <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                  <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

              </asp:GridView>

              <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"

                  SelectCommand="SELECT top 5 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>

      附录-常用格式化公式:

      {0:C}  货币;

      {0:D4}由0填充的4个字符宽的字段中显示整数;

      {0:000.0}四舍五入小数点保留第几位有效数字;

      {0:N2}小数点保留2位有效数字;{0:N2}%   小数点保留2位有效数字加百分号;

      {0:D}长日期;{0:d}短日期;{0:yy-MM-dd}   例如07-3-25;;{0:yyyy-MM-dd}  例如2007-3-25

      11.GridView实现用“...”代替超长字符串:

      解决方法:数据绑定后过滤每一行即可

      for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

              {

                  DataRowView mydrv;

                  string gIntro;

                  if (GridView1.PageIndex == 0)

                  {

                      mydrv = myds.Tables["飞狐工作室"].DefaultView[i];//表名

                      gIntro = Convert.ToString(mydrv["家庭住址"]);//所要处理的字段

                      GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);

                  }

                  else

                  {

                      mydrv = myds.Tables["飞狐工作室"].DefaultView[i + (5 * GridView1.PageIndex)];

                      gIntro = Convert.ToString(mydrv["家庭住址"]);

                      GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 2);

                  }

              } 

      调用的方法:

          public string SubStr(string sString, int nLeng)

          {

              if (sString.Length <= nLeng)

              {

                  return sString;

              }

              string sNewStr = sString.Substring(0, nLeng);

              sNewStr = sNewStr + "...";

              return sNewStr;

          }

      12.GridView一般换行与强制换行:

      首先设置<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" ItemStyle-Width="100" />gridview里有一列绑定的数据很长,显示的时候在一行里面显示,页面拉得很宽。原因是连续英文段为一个整体导致的,在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add("word-break", "break-all")就可以。如果要给所有的列增加此属性:

       protected void Page_Load(object sender, EventArgs e)

          {

              //正常换行

              GridView1.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");

              //下面这行是自动换行

              GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word");

              if (!IsPostBack)

              {

                   bind();//调用数据绑定即可

              }

          }

      总之:善用CSS的word-break:break-all;word-wrap:break-word属性即可,这个属性是通用的对于顽固的南换行问题都可以解决,不局限于GridView。

      13.GridView显示隐藏某一列:

      解决方案:

      public void bind()

          {

              string sqlstr = "select top 5 * from 飞狐工作室";

              sqlcon = new SqlConnection(strCon);

              SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

              DataSet myds = new DataSet();

              sqlcon.Open();

              myda.Fill(myds, "飞狐工作室");

              GridView1.DataSource = myds;

              GridView1.DataKeyNames = new string[] { "身份证号码" };

              GridView1.DataBind();

              sqlcon.Close();

              GridView1.Columns[3].Visible = false;//一开始隐藏

              CheckBox1.Checked = false;//如果不这样后面的代码会把他True

          }

      双击CheckBox1,在CheckedChanged方法里写上代码,最后代码如下:

      protected void CheckBox1_CheckedChanged(object sender, EventArgs e)

          {

               GridView1.Columns[3].Visible=! GridView1.Columns[3].Visible;

               Response.Write("GridView1的第4列现在的显示隐藏状态是:"+GridView1.Columns[3].Visible.ToString());

          }

      注意:CheckBox1的AutoPostBack要True!

      14.GridView弹出新页面:

       <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                              OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"  >

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                  <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                  <asp:HyperLinkField HeaderText="姓名" Text="姓名" DataNavigateUrlFields="姓名" DataNavigateUrlFormatString="Default6.aspx?GoodsID={0}" Target="mainframe" NavigateUrl="~/Default6.aspx" DataTextField="姓名" >

                          </asp:HyperLinkField>

                                  <asp:CommandField HeaderText="选择" ShowSelectButton="True" />

                                  <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                  <asp:CommandField HeaderText="删除" ShowDeleteButton="True" />

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

      DataNavigateUrlFields是链接的字段名,DataNavigateUrlFormatString是路径。

      15.GridView固定表头(不用javascript只用CSS!,很好用)

      代码:

      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.1click-soft.com/tfgjylgw/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      <html xmlns="http://www.1click-soft.com/tfgjylgw/1999/xhtml" >

      <head runat="server">

          <title>GridView固定表头 清清月儿http://www.1click-soft.com/tfgjylgw/21aspnet </title>

              <style>

      .Freezing

         {

         

         position:relative ;

         table-layout:fixed;

         top:expression(this.offsetParent.scrollTop);  

         z-index: 10;

         }

      .Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}

      </style>

      </head>

      <body>    <form id="form1" runat="server">

          <div>                   <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                              OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowCreated="GridView1_RowCreated"  >

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                  <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                  <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                 

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"  CssClass="ms-formlabel DataGridFixedHeader"/>

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>

                          </asp:GridView>

              </div>

          </form>

      </body>

      </html>

      用法:CSS设如上的样式,HeaderStyle加CssClass="Freezing,套住GridView的Div设置高度宽度 <div>16.GridView合并表头多重表头无错完美版(以合并33行举例)

      后台代码:

          protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)

          {

              switch (e.Row.RowType)

              {

                  case DataControlRowType.Header:

                      //第一行表头

                      TableCellCollection tcHeader = e.Row.Cells;

                      tcHeader.Clear();

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[0].Attributes.Add("rowspan", "3"); //跨Row

                      tcHeader[0].Attributes.Add("bgcolor", "white");

                      tcHeader[0].Text = "";

                      tcHeader.Add(new TableHeaderCell());

                      //tcHeader[1].Attributes.Add("bgcolor", "Red");

                      tcHeader[1].Attributes.Add("colspan", "6"); //跨Column

                      tcHeader[1].Text = "全部信息</th></tr><tr>";

                      //第二行表头

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[2].Attributes.Add("bgcolor", "DarkSeaGreen");

                      tcHeader[2].Text = "身份证号码";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[3].Attributes.Add("bgcolor", "LightSteelBlue");

                      tcHeader[3].Attributes.Add("colspan", "2");

                      tcHeader[3].Text = "基本信息";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[4].Attributes.Add("bgcolor", "DarkSeaGreen");

                      tcHeader[4].Text = "福利";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[5].Attributes.Add("bgcolor", "LightSteelBlue");

                      tcHeader[5].Attributes.Add("colspan", "2");

                      tcHeader[5].Text = "联系方式</th></tr><tr>";

                      //第三行表头

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[6].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[6].Text = "身份证号码";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[7].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[7].Text = "姓名";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[8].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[8].Text = "出生日期";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[9].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[9].Text = "薪水";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[10].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[10].Text = "家庭住址";

                      tcHeader.Add(new TableHeaderCell());

                      tcHeader[11].Attributes.Add("bgcolor", "Khaki");

                      tcHeader[11].Text = "邮政编码";

                      break;

              }

          }

      }

      17.GridView突出显示某一单元格(例如金额低于多少,分数不及格等)

      解决方案:主要是绑定后过滤

       GridView1.DataBind();

              for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

              {

                  DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];

                  string score = Convert.ToString(mydrv["起薪"]);

                  if (Convert.ToDouble(score) < 34297.00)//大家这里根据具体情况设置可能ToInt32等等

                  {

                      GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Red;

                  }

              }

              sqlcon.Close();

      前台代码:

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                  <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />

                                

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

              </div>

          </form>

      </body>

      </html>

      18.GridView加入自动求和求平均值小计

      解决方案:    

      private double sum = 0;//取指定列的数据和,你要根据具体情况对待可能你要处理的是int

      protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

          {

             

              if (e.Row.RowIndex >= 0)

              {

                  sum += Convert.ToDouble(e.Row.Cells[6].Text);

              }

              else if (e.Row.RowType == DataControlRowType.Footer)

              {

                  e.Row.Cells[5].Text = "总薪水为:";

                  e.Row.Cells[6].Text = sum.ToString();

                  e.Row.Cells[3].Text = "平均薪水为:";

                  e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();

                 

              }

          }

      前台:唯一的花头就是设置ShowFooter="True" ,否则默认表头为隐藏的!

      <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" OnRowEditing="GridView1_RowEditing"

                              OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound" ShowFooter="True"  >

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:CommandField HeaderText="编辑" ShowEditButton="True" />

                                  <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                  <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                  <asp:BoundField DataField="出生日期" HeaderText="邮政编码"  />

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                  <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />

                                  <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                                

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"  CssClass="ms-formlabel DataGridFixedHeader"/>

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView> 

       19.GridView数据导入Excel/Excel数据读入GridView

      解决方案:

      页面增加一个按钮,单击事件添加如下方法:

      protected void Button1_Click(object sender, EventArgs e)

          {

              Export("application/ms-excel", "学生成绩报表.xls");

          }

          private void Export(string FileType, string FileName)

          {

              Response.Charset = "GB2312";

              Response.ContentEncoding = System.Text.Encoding.UTF7;

              Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());

              Response.ContentType = FileType;

              this.EnableViewState = false;

              StringWriter tw = new StringWriter();

              HtmlTextWriter hw = new HtmlTextWriter(tw);

              GridView1.RenderControl(hw);

              Response.Write(tw.ToString());

              Response.End();

          }

      //如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内

          public override void VerifyRenderingInServerForm(Control control)

          {

          }

      还有由于是文件操作所以要引入名称空间IO和Text

      后台代码:

      using System;

      using System.Data;

      using System.Configuration;

      using System.Web;

      using System.Web.Security;

      using System.Web.UI;

      using System.Web.UI.WebControls;

      using System.Web.UI.HtmlControls;

      using System.Data.SqlClient;

      using System.Drawing;

      using System.IO;

      using System.Text;

      public partial class Default7 : System.Web.UI.Page

      {

          SqlConnection sqlcon;

          SqlCommand sqlcom;

          string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";

          protected void Page_Load(object sender, EventArgs e)

          {

              if (!IsPostBack)

              {

                  bind();

              }

          }

         

          public void bind()

          {

              string sqlstr = "select top 5 * from 飞狐工作室";

              sqlcon = new SqlConnection(strCon);

              SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

              DataSet myds = new DataSet();

              sqlcon.Open();

              myda.Fill(myds, "飞狐工作室");

              GridView1.DataSource = myds;

              GridView1.DataKeyNames = new string[] { "身份证号码" };

              GridView1.DataBind();

              sqlcon.Close();

          }

          protected void Button1_Click(object sender, EventArgs e)

          {

              Export("application/ms-excel", "学生成绩报表.xls");

          }

          private void Export(string FileType, string FileName)

          {

              Response.Charset = "GB2312";

              Response.ContentEncoding = System.Text.Encoding.UTF7;

              Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());

              Response.ContentType = FileType;

              this.EnableViewState = false;

              StringWriter tw = new StringWriter();

              HtmlTextWriter hw = new HtmlTextWriter(tw);

              GridView1.RenderControl(hw);

              Response.Write(tw.ToString());

              Response.End();

          }

          public override void VerifyRenderingInServerForm(Control control)

          {

          }

         

      }

      前台:

      <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" 

                               BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"   >

                              <FooterStyle BackColor="White" ForeColor="#000066" />

                              <Columns>

                                  <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />

                                  <asp:BoundField DataField="姓名" HeaderText="姓名"  />

                                  <asp:BoundField DataField="出生日期" HeaderText="邮政编码"  />

                                  <asp:BoundField DataField="家庭住址" HeaderText="家庭住址"  />

                                  <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />

                                  <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                                

                              </Columns>

                              <RowStyle ForeColor="#000066" />

                              <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />

                              <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left"  CssClass="ms-formlabel DataGridFixedHeader"/>

                              <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

                          </asp:GridView>

              <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="导出" />

      读取Excel数据的代码:这个很简单的

      private DataSet CreateDataSource()

          {

              string strCon;

              strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";

              OleDbConnection olecon = new OleDbConnection(strCon);

              OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);

              DataSet myds = new DataSet();

              myda.Fill(myds);

              return myds;

          }

          protected void Button1_Click(object sender, EventArgs e)

          {

              GridView1.DataSource = CreateDataSource();

              GridView1.DataBind();

          }
