我希望当用户单击 DeleteBox 时删除该行。

使用 RowCommand 事件。

当单击 GridView 控件中的按钮时，将引发 RowCommand 事件。这使您能够提供一个事件处理方法，每当此事件发生时，该方法都会执行自定义例程。

GridView 控件中的按钮还可以调用该控件的一些内置功能。要执行其中一项操作，请将按钮的 CommandName 属性设置为下表中的值之一。

 <asp:gridview id="ContactsGridView" 
          datasourceid="ContactsSource"
          allowpaging="true" 
          autogeneratecolumns="false"
          onrowcommand="ContactsGridView_RowCommand"
          runat="server">

          <columns>
            <asp:buttonfield buttontype="Link" 
              commandname="Delete" 
              text="Delete"/>
            <asp:boundfield datafield="ContactID" 
              headertext="Contact ID"/>
            <asp:boundfield datafield="FirstName" 
              headertext="First Name"/> 
            <asp:boundfield datafield="LastName" 
              headertext="Last Name"/>
          </columns>



        </asp:gridview>




Sub ContactsGridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)

' If multiple buttons are used in a GridView control, use the
' CommandName property to determine which button was clicked.
If e.CommandName = "Delete" Then

  ' Convert the row index stored in the CommandArgument
  ' property to an Integer.
  Dim index As Integer = Convert.ToInt32(e.CommandArgument)

      'Call you delete function here 
    End IF      
 End Sub**strong text**
