Question

我的数据网格有一个DataGridHyperlinkColumn，但是点击那个超链接我没有得到这个值。我的数据网格是，

<datagrid name="datagrid1">
   <column>
      <DataGridHyperlinkColumn Binding="{Binding ID}" Header="ID"  Width="100" >
         <DataGridHyperlinkColumn.ElementStyle>
            <Style TargetType="TextBlock" >
               <EventSetter  Event="Hyperlink.Click" Handler="Hyperlink_Click"  />
            </Style>
         </DataGridHyperlinkColumn.ElementStyle>
      </DataGridHyperlinkColumn>
   </column>
</datagrid>

我将如何在Hyperlink_Click方法中获取Id。？

Answer 1

您可以从ID的{{1}} TextBlock获取DataContext：

private void Hyperlink_Click(object sender, RoutedEventArgs e)
{
    //cast sender to TextBlock, and get it's data context
    var dc = ((TextBlock)sender).DataContext;
    //cast data context to your model type, and get the ID property
    var id = ((YourModelType)dc).ID;
}

或者您可以设置其他答案中建议的Tag TextBlock属性：

<DataGridHyperlinkColumn Binding="{Binding ID}" Header="ID"  Width="100" >
    <DataGridHyperlinkColumn.ElementStyle>
        <Style TargetType="TextBlock" >
            <Setter Property="Tag" Value="{Binding ID}" />
            <EventSetter  Event="Hyperlink.Click" Handler="Hyperlink_Click"  />
        </Style>
    </DataGridHyperlinkColumn.ElementStyle>
</DataGridHyperlinkColumn>

然后你可以在事件处理程序中获得ID值，如下所示：

private void Hyperlink_Click(object sender, RoutedEventArgs e)
{
    TextBlock textblock = (TextBlock)sender;
    string id = (string)textblock.Tag;
}

Answer 2

您可以使用ID设置超链接的Tag属性，并获取此标记值

 private void  Hyperlink_Click(object sender, RoutedEventArgs e)
        {
            HyperlinkButton hlb = (HyperlinkButton)sender;
            if(hlb !=null){
               var id = hlb.tag
            }

        }
