      accordion 定义了有一个item定义 accordionitem.header 中包含 radionbutton 为什么不可选,要切换到别的item后才可选,php自定义header


      <layoutToolkit:Accordion Grid.Row="1" Grid.Column="0" Margin="0,0,5,0" Height="270"??? >
      ??????????? <layoutToolkit:AccordionItem? Tag="bbd"? Selected="AccordionItem_Selected" VerticalAlignment="Center"? Background="LightGray"? x:Name="fly_acc" IsSelected="False"? >
      ??????????????? <layoutToolkit:AccordionItem.Header >
      ??????????????????? <StackPanel Orientation="Horizontal" >
      ??????????????????????? <TextBlock Text="三班排序"/>
      ??????????????????????? <RadioButton Tag="bbd" Content="当日板块" IsChecked="true"? GroupName="r1" /><RadioButton Tag="bbd" Content="一班排序" GroupName="r1" /><RadioButton Tag="bbd" Content="二班排序" GroupName="r1" />
      ??????????????????? </StackPanel>
      ??????????????? </layoutToolkit:AccordionItem.Header>
      ???? <layoutToolkit:AccordionItem.Content />
      ??? </layoutToolkit:AccordionItem>?

      解决方案


      设计就是这样的,选中的AccordionItem会被Lock住,触发UpdateVisualState进而调用VSM来disable元素.如果你觉得这样设计不是很好欢迎到下面的地方提意见:

      private void SetLockedProperties()
      {
      ??? for (int i = 0; i < base.Items.Count; i++)
      ??? {
      ??????? AccordionItem item = base.ItemContainerGenerator.ContainerFromIndex(i) as AccordionItem;
      ??????? if (item != null)
      ??????? {
      ??????????? item.IsLocked = (item.IsSelected && this.IsMinimumOneSelected) && (this.SelectedIndices.Count == 1);
      ??????? }
      ??? }
      }

      ?public bool IsLocked
      {
      ??? get
      ??? {
      ??????? return this._isLocked;
      ??? }
      ??? internal set
      ??? {
      ??????? if (this._isLocked != value)
      ??????? {
      ??????????? this._isLocked = value;
      ??????????? this.UpdateVisualState(true);
      ??????? }
      ??? }
      }

      internal virtual void UpdateVisualState(bool useTransitions)
      {
      ??? if (this.IsLocked)
      ??? {
      ??????? VisualStates.GoToState(this, useTransitions, new string[] { "Locked" });
      ??? }
      ...
      }

      <vsm:VisualStateGroup x:Name="LockedStates">
      ????????????????? <vsm:VisualStateGroup.Transitions>
      ????????????????????? <vsm:VisualTransition GeneratedDuration="0" />
      ????????????????? </vsm:VisualStateGroup.Transitions>
