I've found many posts about this error in this forum as well as other forums, however I have not found a solution that has worked for me yet.My report runs fine in Report Viewer and I can export it to PDF without a problem. The problem occurs if I try running the report or exporting the report again, only 30 seconds later, I receive the session has expired error.There are no images in the report, so setting "AsyncRendering" to False doesn't work for me.I triedsetting <sessionState cookieless="true" /> in my web.config file but that didn't work either.I tried setting me.session.timeout = 120 on my page_load event but that didn't work.All attempts brought me back to the same error. Hopefully some of the ideas above will help other people, but none have worked for me so far. Please let me know if someone knows of a solution/work around to this error.Thanks.
