I have sucessfully redirect one of my page to 404 error page using redirection in sitecore. Problem is when i am selecting any country from dropdown list i am getting below error :
"Invalid postback or callback argument. Event validation is enabled using 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."
I don't want to compromise with security by setting 'enableEventValidation = false'. By doing so its working fine but i am in need of some alternate solution. And, yes my dropdown binding is inside !postback too.
and even I tried to register ClientScriptManager.RegisterForEventValidation method as suggested in one of blog but it did not worked.
Some code part of 404 page is :
