Unsupported File format

[Rieni De Rijke]

Thank you for the new RadRichTextBox.
I installed the new Q1 for 2011 and tried the Telerik Editor example.
Works fine, but... when I try to open or save documents as .docx (or as richtextformat) I get a messagebox: "Unsupported File format".

Office 2010 (Norwegian) is installed.

Hello Rieni De Rijke,

Could you please check if you have added a reference to the following assembly: 
Telerik.Windows.Documents.FormatProviders.OpenXml

For easier extensibility and separation of concerns, RadRichTextBox uses format providers to deal with the import and export of the documents. Here is a list of the currently available format providers and the assemblies they are included in:

• TxtFormatProvider (plain text) – Telerik.Windows.Documents;
• DocxFormatProvider - Telerik.Windows.Documents.FormatProviders.OpenXml;
• HtmlFormatProvider - Telerik.Windows.Documents.FormatProviders.Html;
• XamlFormatProvider - Telerik.Windows.Documents.FormatProviders.Xaml;
• RtfFormatProvider - Telerik.Windows.Documents.FormatProviders.Rtf;
• PdfFormatProvider - Telerik.Windows.Documents.FormatProviders.Pdf.

Note that comments are currently not imported and exported with RTF, but they will be available in the service pack (due in midApril) or in an internal build some time before that.
If you have other questions, do not hesitate to contact us again.

All the best,
Iva

I have the same issue. Also, please note that he and I are trying to run your sample app. So, the question is whether you included references to those DLLs, not us.

You asked if I had added a reference to the following assembly: 
Telerik.Windows.Documents.FormatProviders.OpenXml

I'have added nothing at all. I only tried to run the sample app which is included in the new Q1 2011.
I checked which references are included.
Look here, these references are added to the project:

• TxtFormatProvider (plain text) – Telerik.Windows.Documents;
• DocxFormatProvider - Telerik.Windows.Documents.FormatProviders.OpenXml;
• HtmlFormatProvider - Telerik.Windows.Documents.FormatProviders.Html;
• XamlFormatProvider - Telerik.Windows.Documents.FormatProviders.Xaml;
• RtfFormatProvider - Telerik.Windows.Documents.FormatProviders.Rtf;
• PdfFormatProvider - Telerik.Windows.Documents.FormatProviders.Pdf.

Hi Rieni and Frank,

You are right, there is a issue with some assemblies missing in QSF Examples solution. As a simple workaround you could copy 

• Telerik.Windows.Documents.FormatProviders.OpenXml.dll
• Telerik.Windows.Documents.FormatProviders.Rtf.dll

from <install_folder>/Binaries/WPF to <install_folder>/Demos/Examples.WPF.

Thank for your cooperation and sorry for the inconvenience.

Greetings,

Hi Boby,
I am creating my own application, I have copied the code from RTF page example, and added all the required references. But still I can only save in 'txt' format, and all other formats are popping an  "Unsupported File format" messagebox.
(I have checked if the dlls (Telerik.Windows.Documents.FormatProviders. *****.dll) are being copied to my output folder, and they all exist there). Am I missing something?
thank you,

Ralph Bou Raad.

Hello Rieni De Rijke,

All format providers are loaded by MEF. If you see anything specific that can interfere with it, it's probably the cause. If you can't solve the problem, please get back to us with a demo project so we can further investigate the issue.

All the best,

In our application we are loading the appropriate assemblies in a separate package.  This allows us to shrink the payload of the rest of the application.  For all of the other telerik controls we are using, this works fine.  But with some of the Richtext and RibbonUI dlls needing MEF to load, we are not able to keep those dlls segregated.  Is there some reason this is done this way.  We would much prefer if the control could verify that the dlls have been loaded before attempting to load them up again.

Hi TOM,

By default when trying to resolve its parts MEF is looking in the assemblies present in the directory when the application is running. Currently you cannot change this behavior. However for the next release in a few weeks we will be providing more control over the way MEF is working.
If you would like, you can open a support ticket and elaborate a bit more on your scenario so we could help you further.

All the best,

Did you find a solution for the "Unsupported Fileformat" - problem?

[Boby]

Hello Rieni De Rijke,
We are not sure what exactly your problem is. All format providers are loaded by MEF, this may cause problems if the format providers' assemblies are not in the application directory. Could you please elaborate more on your scenario? Are you experiencing issues with QSF or with another application?
