resettomg tppviewer's page limits

rbuser

I have a custom print preview where the user can filter which records to
display. The report might start with a length of 20 pages and after
filtering might be only 5 pages. However, although the report renders
correctly on 5 pages the viewer appears to think there is still 20 pages
with the last 15 pages being blank. I tried tppViewer.reset with no luck.
Any suggestions? thanks.

After applying the new filter to the report you need to tell the viewer to
regenerate the report:

TppViewer(ppReport1.PreviewForm.Viewer).RegenerateReport;

See the demo below for an example of applying filters during preview.
