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

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

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

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

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