This is not quite a valid PDF file scenario according to PDF file specification. However, we may try handling it in order to show the correct number of pages. When the kid is of type Pages, it should be added to the pages traversal recursion only the first time it is met.
Even small documents (~30 kb) containing images encoded with CCITTFaxDecode filter can take about 10 seconds to be opened. In 2014 Q1 SP1 such documents load faster.

Setting DocumentSource throws NullReferenceException when PdfViewer is hosted in ElementHost.

Run Expected: The document is opened Actual: NullReferenceException is thrown Workaround: the document could be set to the Document property of PdfViewer.

There is a similar question in FAQ for FontForge (https://fontforge.github.io/faq.html#mingliu) where it is described that kaiu.ttf (and probably mingliu.ttf) font does not store the correct outlines and its outlines need special treatment in order to be rendered correctly. The Chinese glyphs are rendered wrong in RadPdfViewer as well. However, Adobe Reader, FoxitReader and ChromeViewer render the glyphs correctly.
Currently, the disabling of the scrolling functionalities in PdfViewer is pretty tricky.
