System.ArgumentException: Invalid postback or callback argument

Hi Guys,


I have ported tthe code from 1.1 to 2.0 and I am getting the following exception. Does anyone have idea about it? I dont want to change the <pages enableEventValidation="true"/> to <pages enableEventValidation="false"/> on every page.

Please let me know soon. Following is the error message...


System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentException: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.


Thanks,

In web.config add this:
<pages enableEventValidation="true"/>
