Get blank report in Crystal Report Viewer when exporting to PDF

Question

I have an application that creates reports in the CrystalReportViewer while at the same time exports a PDF of that report.  I am having a problem in which
performing the export causes the report in the ReportViewer and the PDF report to be blank. They have the header and column labels but no data.  If I
comment out the Me.Export(reportExportOptions) line at the end of the exportPDFReport method the report in the ReportViewer works fine, displaying
data on the report. 
I have other forms that perfrom this same type of function on different reports and work fine.  In fact they use the same exportPDFReport method.  This leads
me to believe that a difference in the reports may be causing the problem.  But I can't figure out why.
I am using .net 3.5 with Crystal Reports 2008 (CR2008) full edition in Visual Studio 2008.  Although the reports that work were probably created using
VS 2005 and the VS 2005 edition of Crystal, and which have since been updated to CR2008.
Has anyone else experienced this problem?  If so, how did you resolve it?
Thanks for any help!

Answer 1

Pretty much. 
Seems I had at one time hard coded a record selection statement that I forgot to remove which caused the report to be blank.  That solved my problem, but there still seems to be an issue in that the Crystal Report Viewer performed differently when I tried to export to PDF (no records displayed) then when I didn't (records displayed).
