The functionality you have described cannot be achieved using RadPdfViewer directly.
However, you may find the FixedDocumentSinglePagePresenter
useful in your scenario. It can be used to display RadFixedPage
's content. If you create a RadFixedDocument by importing a PDF stream with PdfFormatProvider, then you can show the pages in a control of yours that contains FixedDocumentSinglePagePresenter.
The rest of the functionality is up to you as you can change the Page property to show the page you want. You should have in mind that there are some limitations in FixedDocumentSinglePagePresenter compared to the RadPdfViewer.
