Hi All,
I developed CR report using CR 2008, and integrated it with .Net 2.0, Its working fine in all the environments that we have except one environment. I'm not able to See the preview of Crystal report in that Environment but able to export the report to PDF format.
Details Of the Error is mentioned bellow:
My Application is working fine in In-Proc session, here we can see the preview, export to PDf format.
But when we are trying to See the report in Production Environment u2013 WebFarm (NT Cluster+SQL Cluster) which run in SQLSession. i'm not able to see the preview option. But when i'm exporting the same report to PDF format its working fine. Bellow is the error i got while i try for the preview options. kindly tell me solutions for this.

It looks like you might be attempting to serialize the ReportDocument and store it in Session on a StateServer or SQLServer. The ReportDocument is NOT serializable. You can only put it in Session if the <sessionState> is InProc.
