Exporting from custom preview form

  Hello,
  
  I've found a solution for it.
  At first I've had a central reportmodule with a separate previewform. I've moved all the export stuff from the central module to the previewform and now I export from the preview form.
  
  So:
  frxPreview.Export(....)
  
  regards,
  Gebko

  Hi,
  
  I have the same problem with export and... print methods !
  
  After print or export, custom preview is empty.
  
  It's a very embarrassing problem...

  I use theses methods to prepare and preview my report :
  
  frxrEtat.PrepareReport;
  frxrEtat.ShowPreparedReport;
  ...
  frxrEtat.Print
  
  
  To workaround this bug, I've had a new prepareReport and ShowPreparedReport after printing or exporting, but it's not very cool. User must wait because report is rebuilt !

  Printing from a preview windows works well. I've been looking further in my code and I remarked that now I used the methods "print" and "export" directly from the TfrxPreview component instead of using them from the TfrxReport component.
  
  So the former use of the method was the reason that after a print the report was still in the preview window and after an export it dissapears.
  
  When I use these methods from the TfrxReport component I don't use the preview form and then everything is ok.
  
  But strange is that when you print from the preview window there is no flickering of the window and when you use the export method than there is one (a refresh?).
  
  But it now it works the same as with FR2.54, so the user should not see it.

  OK, i've replaced report methods by preview method and it's run perfectly.
  
  I can see a flicker due to a refresh too in FR 3.09
  
  Thanks !
