Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500 解决办法

我的解决办法:
在Web.Config
<system.web>
<pages enableEventValidation="false"/>
</system.web>

转载的解决办法:
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

在 ScriptManager 内添加 EnablePartialRendering="false" 显示详细的错误信息。

如下：
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="false"/>

一般的原因都是页面存在潜在的危险字符 在 页首加入 ValidateRequest="false"

如下：

<%@ Page Language="C#" MasterPageFile="~/MasterPages/CompanyManage.master" AutoEventWireup="true" CodeFile="CompanyIntroEdit.aspx.cs" Inherits="CompanyIntroEdit" Title="Untitled Page" ValidateRequest="false" %>
