Suppress Exporting Crystal Report as PDF IF No Data

Hello,

I batch export several Crystal Reports as PDF using a VB.NET 2003 Windows application.  However, since I am exporting to PDF and not printing, I cannot suppress if there are no records anymore.  The property the report has to suppress printing if no data doesn't apply to exporting as PDF.  Therefore,  I end up with several PDFs that are blank because they did not have any records.

I'm using the ReportDocument (CR)  class and the CR.ExportOptions process to export.  Here's a sample of what I do after the report is ready to be exported.

Dim CR as New  ReportDocument
..
..' provide path to open the report and enter parameters here too.

With CrExportOptions
        ' Set the destination to a disk file
      .ExportDestinationType = ExportDestinationType.DiskFile
      ' Set the format to PDF
      .ExportFormatType = ExportFormatType.PortableDocFormat
      ' Set the destination options to DiskFileDestinationOptions object
      .DestinationOptions = CrDiskFileDestinationOptions
      .FormatOptions = CrFormatTypeOptions
End With
' Export the report to the PDF folder path
CR.Export()

Is there a way to stop the exporting process if the report is blank or has no records?   I was hoping to use something like size property, but I can't find it.

Any help would be tremendously appreciate it.

if you can check the datasource of report if its empty mean no records then you can stop exporting to pdf.
if its not possible for you to directly check datasource for example Dataset then you can get dataset from report document object and see if it  has data then proceed for pdf otherwise stop exporting to pdf.

There is a report property you can check but you must "display" the report then xport it.

I did this when we were displaying reports and tested the record count before making the viewer visible.  If there were no records then I simply displayed that message rather than showing a report.

This will increase processing time since the report is rendered twice.  Once for the hidden display then again for the export.
