HierarchicalDataTemplate 动态菜单 Command 绑定

    <HierarchicalDataTemplate ItemsSource="{Binding ChildrenList}" DataType="{x:Type wpfApplication2:SysMenuItem}" >

      <HierarchicalDataTemplate.ItemContainerStyle>

          <Style TargetType="MenuItem">

              <Setter Property="Command"

                      Value="{Binding DataContext.SysMenuCommand, ElementName=TestMainWindow}" />

              <Setter Property="CommandParameter" Value="{Binding}"></Setter>

          </Style>

      </HierarchicalDataTemplate.ItemContainerStyle>

      <StackPanel Orientation="Horizontal">

          <TextBlock Text="{Binding Title}" />

      </StackPanel>

     <!--使用EventTrigger缺点：1. 点击菜单空白处不能触发事件 

                               2. 有子菜单的不用触发命令，得在命令中判断。

                               3. 使用菜单触发AvalonDock控件动态添加tab，如果拖动一些tab后，点击菜单active存在的tab时，会有莫名Bug(某一区域tabs不能active，重是调回到一个特定的tab)-->

      <!--<TextBlock Text="{Binding Title}">

        <i:Interaction.Triggers>

          <i:EventTrigger EventName="MouseLeftButtonDown">

            <i:InvokeCommandAction Command="{Binding DataContext.SysMenuCommand, ElementName=TestMainWindow}" CommandParameter="{Binding}">

            </i:InvokeCommandAction>

          </i:EventTrigger>          

        </i:Interaction.Triggers>
