Thank you for contacting us!
Generally, the scenario you are describing is not possible using FixedDocumentSinglePagePresenter. Moreover, I would not suggest to use the approach in your project, as we are planning to obsolete it soon and expose a new way of presenting documents as single page that will provide all other functionality like selection, annotations, etc.
Also, the file you are trying to show and navigate into will unfortunately not work very well with RadPdfViewer. The reason for that is that the Action of the internal links in it is not UriAction, which is the only supported as explained here
. We are planning to introduce a way to navigate into such documents soon, but for now these links will unfortunately not work.
I hope the information is helpful! Let us know if you have other questions.
