GridViewColumnHeader.Click，如何檢測哪個列被點擊？

Question

被搞亂了，似乎無法弄清楚。似乎對象發件人實際上是ListView ..所以即使如果我找出如何獲得GridViewColumn作爲一個孩子......我不知道如何區分哪個列實際點擊？

<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? 
}

發件人會ListView但你可以檢查OriginalSource這將是GridViewColumnHeader，可以從它那裏得到柱：

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