I am able to see the report but when I am trying to export the report to EXCEL or any other format it breaks and throws the Session time out error. This happens when I am opening in modal pop up. I tried to export the report using simple aspx page and it worked. What could be the issue? Why reportviewer control is not working in modal pop up box of aspx web page?It throws the following Error:ASP.NET session has expired Description: An unhandled exception occurred during the execution of the current web request.
