若想实现仅在TabControl中的Tab中添加右键菜单，可在XAML中通过使用样式得到：
<TabControl>
<TabControl.ItemContainerStyle>
<Style TargetType="{x:Type TabItem}">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu/> <!-- Define it here! -->
</Setter.Value>
</Setter>
</Style>
</TabControl.ItemContainerStyle>
</TabControl>
但是上面的菜单执行CLICK事件时会无效。把菜单放到控件资源里就好了：
<UserControl.Resources>
<ResourceDictionary>
<ContextMenu x:Key="SheetTabContextMenu">
<ContextMenu.Items>
<MenuItem Name="DeleteSheetMenu" Header="删除" Click="DeleteSheetMenu_OnClick" />
</ContextMenu.Items>
</ContextMenu>
</ResourceDictionary>
</UserControl.Resources>
<TabControl Name="SheetTabControl"> <TabControl.ItemContainerStyle> <Style TargetType="{x:Type TabItem}"> <Setter Property="ContextMenu" Value="{StaticResource SheetTabContextMenu}" /> </Style> </TabControl.ItemContainerStyle> </TabControl>
