Question

我正在创建一个应用程序，它将ASP.NET页面设置为pdf来打印它。我正在使用iTextSharp。它之前在hTextWriter中显示错误，但我添加了EnableEventValidation =＆＃34; false＆＃34;，它超过了该错误并显示了以下错误。它适用于单个网格视图，但不适用于多视图：主视图。编辑：我认为＆＃34;登录＆＃34;脚本与＆＃34; iduser＆＃34;中断此脚本，因为它表明它们在调试时互相矛盾。

导出为pdf后显示的错误：

System.ArgumentException: 'Script control is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl'

我的代码：

1.aspx

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeFile="1.aspx.cs" Inherits="abc"
    EnableEventValidation="false" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="Server">
</asp:Content>


 <input type="button" onclick="PrintDiv();" value="Print" /><asp:Button ID="btnExport" runat="server" 
             OnClick="btnExport_Click" 
             Text="Export to PDF" />

 <td>
                    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
                    <asp:MultiView ID="MainView" runat="server">
                        <asp:View ID="View1" runat="server">

    }

＆＃39;脚本控制＆＃39; x＆＃39;不是注册的脚本控件。必须使用RegisterScriptControl（）注册脚本控件
