Hi, I overrides the method Document.GetPageCount() to dynamically change the amount of pages to be displayed.
However, are there any ways to reflect the change on the PDFThumbView when page count is changed?

Are you meaning you're using double page display mode and changing when show double or single page?
Or something different?
The same about thumbs: have you the way to provide a painted draft about your aim? A picture, a mockup?
