GridView控件“PendingRecordsGridview”解雇事件RowDeleting这是没有处理

我在谷歌搜索有使用此代码删除一条记录与确认一个简单的方法：GridView控件“PendingRecordsGridview”解雇事件RowDeleting这是没有处理

<asp:templatefield HeaderText="Delete"> 
        <ItemTemplate> 
         <asp:Button ID="deleteButton" runat="server" CommandName="Delete" Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this user?');" /> 
        </ItemTemplate> 
       </asp:templatefield>

但是当我运行它，然后单击删除并点击“是”进行确认。出现此错误： GridView的'PendingRecordsGridview'触发了未处理的事件RowDeleting。

有人帮助我:(我也已经尝试添加该代码``OnRowDeleting = “PendingRecordsGridview_RowDeleting”，但没有成功:(

这里是我的GridView全码：！

请修改您的标记和代码以包括​​事件。

<asp:GridView OnPageIndexChanging="PendingRecordsGridview_PageIndexChanging" ID="PendingRecordsGridview" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" OnRowcommand="PendingRecordsGridview_RowCommand" DataSourceID="sd1" BorderStyle="Ridge" BackColor="White" BorderColor="Black" BorderWidth="3px" CellPadding="4" Width="1070px" PageSize="2" AllowPaging="True"> 
     <RowStyle ForeColor="#003399" HorizontalAlign="Center" OnRowDeleting="PendingRecordsGridview_RowDeleting"/>

在后面的代码中添加此方法。

public void PendingRecordsGridview_RowDeleting (Object sender, GridViewDeleteEventArgs e) 
{ 

}

您正在尝试命令名称为删除为您的删除按钮。所以在GridView创建一个行自动删除事件....

您需要更改从命令参数删除别的东西像Delete_Product或任何...
