I have a problem with export to PDF from a report server. When exporting to PDF from the report viewer control in a ASP.Net web site written in VS2010 and C# for a certain report in the general case it works fine. However, with certain parameters passed to this same report it outputs a corrupted PDF file.
One peculiarity is that this parameter combination that corrupts the PDF file is the one that outputs the most amount of data. All other render formats work fine in all scenarios.
Thanks so much for your help.
I was using Adobe PDF Viewer - latest version. Turns out the issue is fixed in Cumulative Update 6 of SSRS 2008 R2. Installing Service Pack 2 fixed the problem.
