问题描述

 < asp 

我在谷歌搜索了一个简单的方法来删除一个记录, :templatefield HeaderText =删除>
< ItemTemplate>
< asp:Button ID =deleteButtonrunat =serverCommandName =DeleteText =DeleteOnClientClick =return confirm('您确定要删除此用户?'); />
< / ItemTemplate>
< / asp:templatefield>

但是当我运行它并单击删除并单击是确认。这个错误出现:
GridView的PendingRecordsGridview触发了事件RowDeleting,它没有被处理。

有人帮助我:(我也试过添加这段代码



以下是我的gridview完整代码:

解决方案

请修改您的标记和代码以包含 OnRowDeleting 事件

 < asp:GridView OnPageIndexChanging =PendingRecordsGridview_PageIndexChanging PendingRecordsGridviewrunat =serverAutoGenerateColumns =FalseDataKeyNames =IDOnRowcommand =PendingRecordsGridview_RowCommandDataSourceID =sd1BorderStyle =RidgeBackColor =WhiteBorderColor =BlackBorderWidth =3pxCellPadding = 4Width =1070pxPageSize =2AllowPaging =True> 
< RowStyle ForeColor =#003399Horizo​​ntalAlign =CenterOnRowDeleting =PendingRecordsGridview_RowDeleting/>

在后面的代码中加入这个方法。



< pre $ public void PendingRecordsGridview_RowDeleting(Object sender,GridViewDeleteEventArgs e)
{

}


I've searched in google there's an easy way to delete a record with confirmation using this code:

<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>

But when i run it and click delete and clicking "yes" to confirm. this error appears: The GridView 'PendingRecordsGridview' fired event RowDeleting which wasn't handled.

Somebody Help me :( i've also tried adding this code ``OnRowDeleting = "PendingRecordsGridview_RowDeleting" but no success! :(

Here's my gridview full code:

解决方案

Please modify your markup and code to include the OnRowDeleting event.

<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"/>

On the code behind add this method.

public void PendingRecordsGridview_RowDeleting (Object sender, GridViewDeleteEventArgs e)
{

}
