如何在TabControl中响应右键鼠标（添加一个ContextMenu就可以了），如何让在tab标签处右键菜单和在内容处右键菜单显示不同的菜单？

下面的代码演示的就是这种情况 (TabAndContextMenuDemo1)

<TabControl Name ="ta1" >

        <TabItem Name="backgroundcolor" Header="Choose a Background Color" Content = "Some content about background colors.">

          <TabItem.ContextMenu >

            <ContextMenu  >

              <MenuItem Header="Red" Name="testRed" Click="MyMenuHandler"/>

              <MenuItem Header="Blue" Name="blue" Click="MyMenuHandler"/>

              <MenuItem Header="Yellow" Name="yellow" Click="MyMenuHandler"/>

            </ContextMenu>

          </TabItem.ContextMenu>

        </TabItem>

 

        <TabItem Name="Item2" Header="Casf" Content = "it2">

          <TabItem.ContextMenu >

            <ContextMenu  >

              <MenuItem Header="1" Name="a" />

              <MenuItem Header="2" Name="b" />

              <MenuItem Header="3" Name="c"/>

            </ContextMenu>

          </TabItem.ContextMenu>

        </TabItem>

        <TabControl.ContextMenu>

          <ContextMenu >

            <MenuItem Header="12" Name="d" />

            <MenuItem Header="sdf" Name="e" />

            <MenuItem Header="void" Name="f" />

          </ContextMenu>

        </TabControl.ContextMenu>

      </TabControl>
