I try to code an application that splits a big pdf document in serveral small pdf documents. In this case I use two GdViewer controls and two ThumbnailEx controls. One for the big pdf document and one for the new generated document. The ThumbnailEx displays the pages by using the "LoadFromGdViewer"-method.
The user can move each page of the big pdf document to the new one - but the new page is not displaying in the viewer. So I decided to set the source of the pdf document again:
This works fine so far. But the performance is realy bad and it slows further down by the amount of pages.
Are there better ways to handle this?
