GridViewColumnHeader.Click，如何检测单击了哪个列？

Question

一直在搞乱这个，似乎无法搞清楚。似乎对象发送者实际上是ListView ..所以即使我弄清楚如何将GridViewColumn作为一个孩子...我不知道如何区分实际点击了哪个列？

<ListView x:Name="SingleTweet_ListView" 
          ScrollViewer.HorizontalScrollBarVisibility="Disabled" 
          MouseLeftButtonUp="SingleTweet_ListView_MouseLeftButtonUp"
          Height="200" Margin="5,5,5,5" FontSize="12" 
          GridViewColumnHeader.Click="GridViewColumnHeaderClickedHandler">
   <ListView.View>
      <GridView>
         <GridViewColumn Header="Screen Name"
                         DisplayMemberBinding="{Binding Col1}" Width="112"/>
         <GridViewColumn Header="Tweet"
                         DisplayMemberBinding="{Binding Col2}" Width="623"/>
      </GridView>
   </ListView.View>
</ListView>

void GridViewColumnHeaderClickedHandler(object sender, RoutedEventArgs e)
{
    MessageBox.Show(((GridViewColumn)sender).Header.ToString());
    //error cus the sender is actually the listview?
}

发件人将为ListView，但您可以检查OriginalSource GridViewColumnHeader，并且可以从中获取列：

MessageBox.Show(((GridViewColumnHeader)e.OriginalSource).Column
                 .Header.ToString());
