GoToPage() method is not working correctly in some cases when called in DocumentChanged event handler. The known cases are described below:

   1. When RadPdfViewer and the document are loaded initially and document is set through the RadPdfViewer.Document property.
Workaround: DocumentSource property could be set (in XAML or in code-behind) instead of the Document property. If the Document property is used, this should be done after RadPdfViewer is loaded.

    2. When the ScaleMode is changed in DocumentChanged event handler and then GoToPage() method is called in the same event handler.

When text is exported from PDF document using the TextFormatProvider (it's also used internally for the Copy operation), it is automatically split to lines using the vertical position of the words on the page, and small tolerance. 

Currently the tolerance is hard-coded to 0.1 pixels, which is not suitable for documents which contains scanned and OCR-ed text, and there the text lines could be slightly inclined. The result is that words on one slightly inclined line are recognized as if they are on separate lines.

Matte color is used for preblending images with some background color, using the SMask. Matte color is specified using the optional 'Matte' entry for the SMask object.

See PDF 1.7 specification, page 554-555:

Matte
array
(Optional; PDF 1.4) An array of component values specifying the matte color with which the image data in the parent image has been preblended. The array consists of nnumbers, where n is the number of components in the color space specified by the ColorSpace entry in the parent image’s image dictionary; the numbers must be valid color components in that color space. If this entry is absent, the image data is not preblended.

Currently, when we parse inline image dictionaries we rely on the assumption that the colorspace will be PdfName. However, there are files with complex colorspaces that are PdfArray and InvalidCastException is thrown. All the content after this exception is lost and not visualized by RadPdfViewer.

"Save As" is common functionality in most of the popular PDF Viewers. It should save the currently loaded document to a file.

Workaround: Currently there is SDK demonstrating how to add such functionality: https://github.com/telerik/xaml-sdk/tree/master/PdfViewer/PdfViewerCustomSaveCommand

Available in R3 2017 Official Release Version.

A pop-up annotation displays text in a pop-up window for entry and editing. It typically does not appear alone but is associated with a markup annotation (its parent annotation) and is used for editing the parent’s text.

If you search in a very large file and there are no matches of the string you're searching for or the matches are very far from the start (e.g. on the 10 000th page), the search takes a lot of time. The scenario can also lead to a crash.

Consider adding a progress bar showing on which page we're currently searching and implementing possibility to cancel the search.

With the current implementation, it takes seconds to decode and display JPEG with several megapixels (for example size 4000 x 2000 pixels). The memory consumption when decoding such images also needs improvements.

Workaround: Custom DctDecode filter may be implemented and registered in RadPdfViewer. The attached demo shows how this may be achieved by using BitmapImage class to decode the JPEG images instead of the default RadPdfViewer's JpegDecoder.

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.

The default WPF PrintDialog cannot print asynchronously when it is shown in UI. However, you may see the demo in this forum post showing how to create custom PrintDialog and perform async printing with it:
