Answer 1

请注意 错误 信息“DetailsView1_ItemUpdating”的重载均与委托“System.Web.UI.WebControls.DetailsViewUpdateEventHandler”不匹配源错误

然后检查一下<asp:DetailsView ID="DetailsView1" runat="server" CssClass="gwcss" BorderWidth="3px" DataKeyNames="fld_id" 行 7: AutoGenerateRows="False" DataSourceID="SqlDataSource1" OnItemUpdated="DetailsView1_ItemUpdated" OnItemUpdating="DetailsView1_ItemUpdating"> 中的在后台DetailsView1_ItemUpdating
方法的参数是否正确。
可以改写成object sender, EventArgs e试试。
