Render Print preview page on demand

Postby egrobler » September 7th, 2010, 9:26 pm

Thank you for the wonderful print preview component.

I want to print a list of test questions and the list may contain 1000 pages.
Is it possible to add 1000 blank pages and then only render them when a thumbnail/preview is visible or the page needs to be printed?

Something like:
for i := 0 to PagesInTest-1 do PrintPreview.NewPage;
and then on demand something like:
PrintPreview.PaintWinControl(40,40, RenderTestPage(PageNo));

Thanks and Regards
Eric

When user changes the current page the OnChange event occurs. You can use this event to fill the blank page with the actual content (Use BeginReplace method).
