楼主DoNotTomcat（TOM）2003-08-01 10:51:14 在 .NET技术 / ASP.NET 提问

Sub MyDataGrid_Delete(Sender As Object, E As DataGridCommandEventArgs)
.....
MyCommand.Connection.Open()
MyCommand.ExecuteNonQuery()
MyCommand.Connection.Close()
BindGrid()
End Sub

在此过程中，我想在用户点击“删除”时，首先弹出“真的要删除吗？”，然后让用户选择“是”和“否”的对话框，选择“是”，则删除，“否”则不删除。不知用代码如何实现？问题点数：20、回复次数：14Top

you can use js:
function yourConfirm()
{
if(confirm("真的要删除吗")
{
yourserver.click()
}
else
{
return;
}
}Top

<asp:Button id="btnDelete" onClick="javascript:return window.confirm('确定删除吗?')" >
这句话在 <Columns></Columns>会出现错误的，不认这个Button吧？Top

<img border=0 alt='Delete record' src=img/Delete.gif onclick="JavaScript:return confirm('确实删除？')">

打开dataGrid 的属性在删除按纽的“文本”中加入上面这句话！！Top

1、
Sub DataGrid_ItemCreated(ByVal Sender As Object, ByVal e As DataGridItemEventArgs) Handles myDataGrid.ItemCreated 这句话的错误是：Handles clause requires a WithEvents variable。
2、
<img border=0 alt='Delete record' src=img/Delete.gif onclick="JavaScript:return confirm('确实删除？')"> 究竟写在哪里？俺是新手，别笑话，对javascript不是很明白，请多指教。

试试吧，放在datagrid属性生成器中添加按钮列然后再text属性中加上下面的就好了！
在DataGrid1_ItemCommand事件中
if (e.CommandName == "Selectupdown")
{

}

<div id="de" onclick="JavaScript:return confirm('确定要删除吗？')"><center>删除</div>Top
