Currently the editing methods of RadRichTextBox and RadDocumentEditor work with the current DocumentSelection and CaretPosition for the current RadDocument. In order to execute an editing action on specific range/position, current selection/position should be moved, which is not always desirable. Also, as a side effect, when moving current selection or position, the scroll offset of the document shown in RadRichTextBox is changed.
Think of the following approaches:
- Do not scroll the document around when API methods are executed. There is convenient API which could be called to scroll the document when needed. (This will fix the problem only partially). 
- Provide version of the IDocumentEditor methods that accept DocumentSelection or DocumentPosition as parameters, and work with them instead of with the RadDocument.Selection and RadDocument.CaretPosition, similar to InsertFragment(DocumentFragment documentFragmentDocumentPosition documentPosition) and InsertInline(Inline inlineDocumentPosition documentPosition).

Exporting documents that contain PNG images SMask and ImagesDeflaterCompressionLevel is set to a non-default value may produce a document in which those images are not processed correctly by Adobe reader.

The exception is thrown in RadDocument.IsInNonEditableRange() method, which is called before measuring the document. When using a format provider, the error is thrown but the document can still be opened in RichTextBox. In binding scenario, the document is not imported.

Workaround: Ensure the document is measured before assigning it to RadRichTextBox.

Hi Telerik,

We are converting XAML content into PDF file with below code.

private byte[] Xaml2Pdf(string xamlContent)
		XamlFormatProvider xamlFormatProvider = new XamlFormatProvider();
		PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
		PdfExportSettings exportSettings = new PdfExportSettings();
		exportSettings.ContentsCompressionMode = PdfContentsCompressionMode.Automatic;
		exportSettings.ContentsDeflaterCompressionLevel = 9;
		exportSettings.DocumentInfo = new PdfDocumentInfo() { Producer = "ALIS", Author = "ALIS", Creator = "ALIS" };
		exportSettings.ImagesCompressionMode = PdfImagesCompressionMode.Automatic;
		exportSettings.ImagesDeflaterCompressionLevel = 9;
		pdfFormatProvider.ExportSettings = exportSettings;

		byte[] content = pdfFormatProvider.Export(xamlFormatProvider.Import(xamlContent));

		return content;
When we convert attached XAML content with above code it will gives an output pdf file but when we open pdf file into Adobe Reader DC it will display some error message before opening it.

Currently we are using 2016.2.905.45 version.

Previously when we was use 2016.1.302.45 version at that time we didn't notice same issue.

Please assist.

Thank you.

The generated ImageSource is associated with the import thread, while the UI invokes layout logic, which depends on that image, on the main thread. This causes a cross thread access exception.

Adding bookmarks with the same name programmatically always returns the first one in case use attempts to navigate to it using the Bookmarks dialog. 

Workaround: Remove the bookmark before adding a new one with the very same name.

If I setup the richtextbox content through the UI as shown in P1.png and try to restore it by pasting the generated html, I get instead P2.png. Expected to be the same. 

I attached the sample project. We're using the recommended settings to use the same html in telerik reports, but can't find the reference on your site, it used on the on this link

Finding text with regex for the last paragraph is not possible. This is caused by the fact that the search treats the last paragraph symbol as the last paragraph.

The text for the Documents_SpellCheckingDialog_ChangeAll key must be "Changer tout" instead of  "Chanter tout".

Character properties applied on the last paragraph symbol for a paragraph in a list, e.g. font size, are not exported to HTML when StyleExportMode is Inline. 

As a side effect, when the document is imported back, and the text of the bullet is deleted, its properties switch back to the default ones.

Workaround: Change the styles to export as inline properties:
htmlProvider.ExportSettings.StylesExportMode = StylesExportMode.Classes;
Please be aware that this may cause side effects, as described in this issue: RichTextBox: Character properties of the paragraph symbol are exported to HTML for the whole list item when StyleExportMode is Classes
