A potentially dangerous Request.QueryString value was detected from the client when sending html markup from jquery post call to asp.net page -

-

i m making ajax call using jquery asp.net page acts ajax server page save data sending in query string. in asp.net page when trying read querystring getting error:

a potentially dangerous request.querystring value detected client...

i have set validaterequest="false" in page. dont want set pages. did in page level instead of config level:

  var content = "<h3>sample header</h3><p>sample para</p>"   content = encodeuricomponent(content);   var url = "../lib/ajaxhandler.aspx?mode=savecontent&page=home&ltxt=" + content;       $.post(url, function (data) {         //check return value ,    });

and in asp.net page:

 <%@ page language="c#" autoeventwireup="true" codebehind="ajaxhandler.aspx.cs" validaterequest="false" inherits="myproject.lib.ajaxhandler" %>

but when sending plain text instead of html markup, works fine.

if asp.net 4, there breaking change validaterequest. see this stackoverflow question more information on requestvalidationmode.
