Hello Zhang,

RadRichTextBox uses FormatProviders in order to open and save documents in different file formats. They are separated in different assemblies as listed here and are loaded by MEF. SaveCommand and OpenDocumentCommand check the registered format providers just before showing the SaveFileDialog and OpenFileDialogs respectively.

Could you check if you have added references to the assemblies described in the second article? If you have and are still not able to use the format providers, the reason is probably that MEF has not been able to load the assemblies (e.g. this could happen if library caching is enabled). In that case, you can register the format providers manually as described here.

I had this problem also - in my case it was library caching that was the problem.
