首先用模板列：
<asp:TemplateColumn HeaderText="删除">
<HeaderStyle Width="80px"></HeaderStyle>
<ItemTemplate>
<asp:LinkButton id="LinkButton" runat="server" Width="50px" ForeColor="Red" CommandName="Delete">删除</asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn>
后台：
VB:
Sub dgrd_ItemCreated( s As Object, e As DataGridItemEventArgs )
Select Case e.Item.ItemType
Case ListItemType.Item, ListItemType.AlternatingItem
Dim links As LinkButton
links = e.Item.FindControl("btnDelete")
links.Attributes.Add("onclick", "return confirm('你是否确定删除?');")
End Select
End Sub
C#:
private void dgrd_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
switch(e.Item.ItemType)
{
case ListItemType.Item:
case ListItemType.AlternatingItem:
case ListItemType.EditItem:
{

LinkButton btnDelete=(LinkButton)e.Item.FindControl("btnDelete");

btnDelete.Attributes.Add("onclick", "return confirm('你是否确定删除?');");
break;
}
}
}
