?注：選用ExportControl（）方法時

提示：“控件“GridView1”必須放在具有 runat=server 的窗體標記內”，則需在頁面中重寫Page基類的VerifyRenderingInServerForm方法：

public override void VerifyRenderingInServerForm(Control control){// Confirms that an HtmlForm control is rendered for}

MSDN對該方法的解釋如下：

必須位于 <form runat=server> 標記中的控件可以在呈現之前調用此方法，以便在控件被置于標記外時顯示錯誤信息。發送回或依賴于注冊的腳本塊的控件應該在?Control.Render?方法的重寫中調用此方法。呈現服務器窗體元素的方式不同的頁可以重寫此方法以在不同的條件下引發異常。

如果回發或使用客戶端腳本的服務器控件沒有包含在 HtmlForm 服務器控件 (<form runat="server">) 標記中，它們將無法正常工作。這些控件可以在呈現時調用該方法，以在它們沒有包含在 HtmlForm 控件中時提供明確的錯誤信息。

開發自定義服務器控件時，通常在為任何類型的輸入標記重寫 Render 方法時調用該方法。這在輸入控件調用?GetPostBackEventReference?或發出客戶端腳本時尤其重要。復合服務器控件不需要作出此調用。

? ? ? 2.提示：******，則需在前臺頁面添加“EnableEventValidation="false"”，如：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="****.aspx.cs" EnableEventValidation="false" Inherits="**.***.****" %>
