  I know this is the most common error, where i found numbers of solutions tried all but still I am facing the same error. 

  Here is my web,config

  <pages enableViewStateMac="false" enableEventValidation="false" enableViewState="false"></pages>

  I am using jQuery Ajax to post the data and save the information in my database. As well as in some cases I have used AjaxMethods using Ajax.dll

  to post the data to server without complete Postback.

  I place a Usercontrol which has Listview binding to it on Load using. ListView is also given DatakeyNames property which is a global control available throughout the website on all pages. 

  Now when i do postback using from one page to another (where i have a grid view with DatakeyNames property) and on click of this page also i do the same PostBack for thrid page. I get this error. But if without going to the page which contains GridView i do not get the error. So what will be my problem.

  Sorry for such horrible english I hope you will understand what i am trying to explain.
