前台代码：

<asp:DataList ID="DataListResume" runat="server" OnItemDataBound="DataListResume_ItemDataBound"
    OnItemCommand="DataListResume_ItemCommand" DataKeyField="HR_ResumeInfoId">
    <HeaderTemplate>

            Response.Write("<script>alert(" + ItemId + ");</script>");
            HR_ResumeInfo_Provider.DeleteHR_ResumeInfos(ItemId);
            BindResume();
        }

        protected void LBDelete_Command(object sender, CommandEventArgs e)
        {
            LinkButton lbDelete = (LinkButton)sender;
            string ItemId = lbDelete.CommandArgument.ToString();
            Response.Write("<script>alert(" + ItemId + ");</script>");
            HR_ResumeInfo_Provider.DeleteHR_ResumeInfos(ItemId);
            BindResume();
        }

        protected void DataListResume_ItemCommand(object source, DataListCommandEventArgs e)
        {
            if (e.CommandName == "TheDelete")
            {
                string ItemId = DataListResume.DataKeys[e.Item.ItemIndex].ToString();
                Response.Write("<script>alert(" + ItemId + ");</script>");
            }
        }
