I am using ASP.Net 4.0 and it throws an error only in a single page and single browser. This error occurs only IE whenever in other browsers i.e. (Chrome, firefox, safari, opera) in all of them this page runs properly and working fine but this page gives an error in and only in IE when we call any button event of this page in IE but if we are using other than IE it works fine. I am too much stuck why this error occurs only in IE and i tried lots to getting this error but i failed. Can anyone help me out i am describing this error information:

being loaded must match the control tree that was used to save
viewstate during the previous request. For example, when adding
controls dynamically, the controls added during a post-back must match
the type and position of the controls added during the initial
request. Description: An unhandled exception occurred during the
execution of the current web request. Please review the stack trace
