Remarks

File extension determines the document format. The following file extensions are recognized:

DOC, DOCX, RTF, TXT, HTM, HTML, MHT, XML, EPUB;
ODT - non-encrypted files only.

If the file is in a different format than its extension indicates, or encrypted, it is not loaded. However, you can subscribe to the RichEditControl.InvalidFormatException event which occurs in this situation and examine the RichEditInvalidFormatExceptionEventArgs.Exception property to find out a reason for not loading a document.

Tip

Determine a moment when the document model can be safely modified using the RichEditControl.DocumentLoaded event. Handle the DocumentLayout.DocumentFormatted event to check the loaded document’s layout.
