我想要當用戶點擊DeleteBox刪除那一行。

使用RowCommand事件。

在GridView控件中單擊按鈕時會引發RowCommand事件。這使您可以提供事件處理方法，以便在發生此事件時執行自定義例程。

GridView控件中的按鈕也可以調用控件的一些內置功能。要執行這些操作之一，請將按鈕的CommandName屬性設置爲下表中的某個值。

<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**
