Add a navigation pane to view attachments under a pdf. it is possible to have various attachments under a pdf file, such has another pdf. For example, when converting an email with attachments, the resulting pdf has attachments. RadPdfViewer has no possibility to view those right now. Could be an event and let the calling program manage this. For our needs, I would like an event, because our attached files are also pdfs, so I could open them in a new tab
