Thank you for contacting us.
Currently the RadPdfViewer
does not support this feature. We already have logged in our Feedback portal, so you can track its progress, subscribe for status changes and add your vote/comment to it on the following link - ADD. RadPdfViewer- add bookmarks functionality
You can not call the GetAllBookmarks
method because it does not exist. In our code there is a method with same name, but it can be called by another control - RadRichTextEditor
Hope this will help you. Let me know if you have any other questions
