最近在ASP.NET中使用AJAX的时候，碰到这么一个错误，错误的全称是：
Sys.WebForms.PageRequestManagerParserErrorException:The message received from the server
count not be parsed.Common causes for this error are when the response is modified by calls to response.Write(),response filters,HttpModules,or server trace is enabled.
Details:Error parsing near '|
解决方法：
“设置页面属性EnableEventValidation="false" 就可以了”。
