我正在使用Windows Phone Control工具包中的ContextMenu.想知道如何知道列表中的哪个列表项被按下？似乎我可以知道选择了哪个上下文菜单,但我无法知道操作哪个列表项.请帮忙.谢谢!

        <DataTemplate x:Key="ListItemTemplate">
            <StackPanel Grid.Column="1" VerticalAlignment="Top">
                <TextBlock Tag="{Binding Index}"  Text="{Binding SName}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" />
              <toolkit:ContextMenuService.ContextMenu>
                <toolkit:ContextMenu>
                  <toolkit:MenuItem Header="Add to playlist" Click="Move_Click"/>
                </toolkit:ContextMenu>
              </toolkit:ContextMenuService.ContextMenu>
            </StackPanel>

        private void Move_Click(object sender, RoutedEventArgs e)
    {
        String name = (string)((MenuItem)sender).Header;
        // how to know which index of the item is targeted on
    }
