To reproduce:
When document that contain a specific formatting is imported there is some missing text.

radPdfViewer1.PdfViewerElement.Find("keyword", PageNumber);

Resolution: 
You can use the following code snippet: 
radPdfViewer1.PdfViewerElement.Find(string text, int pageNumber)

Description: Single Page View Displays one page at a time, with no portion on other pages visible.

Add the ability to recognize if the document is in portrait or landscape mode when printing.

To reproduce:
- Open the attached file with RadPdfViewer.

To reproduce:
-add RadPDFViewer and load a document that has an image for the background and some text over it. As a result RadPDFViewer does not render correctly the file.

There is no workaround for this issue.

FIX. RadPdfView - dragging RadPdfViewer to a form does not include the TelerikCommon assembly

To reproduce: When load the document, the text from file is not visible

PdfViewer throws a "Position is out of range" exception when scroll.

PdfViewer - does not arrange correctly the layout of some pages.

PdfViewer - throws NullReferenceException in GetPages method of PdfContentManager.

PdfViewer - throws System.OutOfMemoryException in PdfElementsRenderer.RenderImage when the scroll is moving fast.

When you open a PDF file with the Rad PDF reader the header of the file is not being dispalyed. Only the body gets displayed.

Add bookmarks functionality

Add UI for adding comments and ability to save them. Comments are represented in the document model as text annotations (annotations with Subtype Text). 

This issue can be observed when the text is too big to fit in cell.

When clicking on link annotations pointing to destinations in the document, and the "Fit one full page to window" mode is activated, the document is not scrolled exactly to the destination.

The issue can be reproduced only in Single Page Presenter mode and when the Top and Left values of the passed parameter are greater than 0.

The problem can also be observed by invoking directly GoToDestination method, as the problem is inside it.
