一般GridView的刪除鈕可以在Columns加上ButtonField或CommandField欄位來完成，但是這二種方式的刪除鈕都沒有屬性可以加入刪除的提示訊息，以下的範例將說明如何在GridView加上刪除提示訊息。

在GridView的Columns中加入一個ButtonField，然後在GridView的RowDataBound事件中，找到按鈕並加入刪除的訊息。

03             <Columns>
04                 <asp:ButtonField ButtonType="Button" CommandName="Delete" Text="刪除" />
05                 <asp:BoundField DataField="EmployeeID" HeaderText="EmployeeID" ReadOnly="True" SortExpression="EmployeeID" />
