Hello,
Since we migrated to new servers (Windows Server 2012 R2) and changed our applications to target .NET Framework 4.6.1 (with absolutely no changes to our reports), exporting to PDF from the ASP.NET CRViewer control results in all blank pages.
- The viewer displays the report just fine.
- The number of pages in the PDF matches the number of pages shown in the viewer, but every single PDF page is blank.
- Exporting to other types, such as Microsoft Word, works fine (so we have a workaround, though there are some formatting issues with Word-targeted reports).
- Exporting directly to PDF from code also works fine, so the PDF problem is limited to the viewer control's print/Export to PDF functionality.
- This problem still exists after upgrading to SP 16. Reverting back to an older CR service pack (14 or 15) doesn't resolve the issue, hence the guess that this problem is related to .NET Framework 4.6.1.
Questions
- Is anyone else with applications targeting .NET 4.6.1 able to export to PDF from the ASP.NET viewer successfully?
- What could I check to track down the problem?
- What can I provide to the CR development team to help them track down the problem?
Thanks,
Andre
