Hi,
Can we restrict the scrolling of pages to a few pages.
eg. If there is a pdf of 20 pages. I want to view that pdf from 4 to 10 page only and restrict fro viewing other pages.

Which platform your are interested in?

iOS

Hi,

there is not a specific method to do that, but you can customize the SDK to reach your needs, in this case you can try different ways:
- Edit the pageCount method of PDFDoc in PDFObjc class and return the last page to show (e.g.. if your pdf file has 20 pages, you can return 5 in this method to show only 5 pages and thumbnails).
- Open the pdf file to minimum page of your range.
- Check if the current page is in your range in OnPageChanged method of PDFView class and use vGoto method to limit the pdf navigation.

I need to achieve this in scroll view. Also i don't want to alter the pages of the original document. I just want to give the user access only to the set of pages. eg. in a pdf of 10 pages. i want to give the user access to pages 2 to 4.

You can do it with the vGoto method as described in points 2 and 3
