想找出   DeleteReply   在后台加上删除前的确认框

[解决办法]
<SCRIPT LANGUAGE= "JavaScript ">
<!--
function onDelete()
{
if (confirm( "确定删除数据吗? "))
return true;
else
return false;
}
//-->
</SCRIPT>


<asp:LinkButton onclick= "onDelete(); " id= "DeleteReply " CommandName= "delete " Runat= "server " Visible= ' <%# CanModerateForums %> '>
[解决办法]
DataItemBound事件里
[解决办法]
我觉得应该在DataItemBound里面判断一下是否为DataGrid的Header或Footer,用e.item.ItemIndex判断
[解决办法]
当然还要判断ItemType了
