DocxFormatProvider no longer appears to be an IDocumentFormatProvider

[Jason]

Good morning,
My company is looking at using the RadRichTextBox control for rendered, editing, and exporting Docx documents. I am attempting to write a small test app as a proof-of-concept but I've hit a problem I can't get around. In all of the demos/tutorials I am seeing online they are creating a DoxFormatProvider and using it to create a document like the following:

using( Stream readStream = dialog.OpenFile() )
{
   IDocumentFormatProvider provider = new DocxFormatProvider();
   RadDocument = provider.Import( readStream );
}

Unfortunately what I am seeing is that DocxFormatProvider will not cast to an IDocumentFormatProvider. DocxFormatProvider appears to be a BinaryFormatProviderBase<RadFlowDocument> found in the Telerik.Windows.Documents.Flow assembly. The DocxFormatProvider returns a RadFlowDocument rather than a RadDocument which I have been unable to find a way to get a RadFlowDocument to work in the RadRichTexTextBox control.

It appears like all other providers have their own DLL following the pattern Telerik.Windows.Documents.FormatProviders.XXX.dll where XXX is the provider type but I do not see a Docx DLL. The assemblies I am working with are 2014.2.729.45. Any guidance would be greatly appreciated. Thanks!

Hello Jason,

Indeed, the Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider class is used to import/export RadFlowDocument instances. The class is related to the functionality of the RadWordsProcessing library and would not work with RadRichTextBox.

In order to create a RadDocument, you need to use the format provider located in the Telerik.Windows.Documents.FormatProviders.OpenXml.dll in the Telerik.Windows.Documents.FormatProviders.OpenXml.Docx namespace. Please note that a reference to the Telerik.Windows.Zip.dll is required as well to ensure the provider works properly.

I hope this helps.

Regards,
Petya

Even though this is the WPF forum, I have encountered the same problem in a WinForms application.  The error I am getting is that "Value of type 'RadDocument' cannot be converted to 'RadDocument'.  I have attached an image with the code and error.

I tried using the code directly from this page ("http://www.telerik.com/help/winforms/richtexteditor-import-export.html") and simplified it to try to eliminate the error.  No luck.  Any suggestions?

UPDATE:  The issue was apparently caused by the fact that my sample application was using both a RadFlowDocument and RadDocument and VS intellisense was grabbing the wrong library.  It was using Telerik.Windows.Documents.... instead of Telerik.WinForms.Documents....  When I directly referenced the namespaces everything worked.  Hope this helps someone else!
