Hi, I've got the Q3.2010 RadControls and I've implemented an editor using the RichTextBox.
What I need to be able to do is open a .docx file, and then use the RichTextBox's built in functionality to export to Html.
This works perfectly with the reference document I was originally testing with.
However, it turns out that the editor breaks with almost every other document I try.
It seems to have something to do with images and/or certain formatting.
The documents in question open just fine in the editor, and are displayed correctly.
When I try to export to HTML it breaks.
Below is the code I am using to export:
This code throws out an error for most documents. The error varies slightly, but below is an example of the error:
For another document I tried, I get the below error stack:
Please advise as to what I could try to get this working? I need to deliver this solution ASAP.
Thanks.

Hi Daryl,

This problem occurs when the ImageExportMode of the HtmlFormatProvider is set to UriSource and an image doesn't have a URI. As this action is invalid, an exception is thrown. However, in the next minor release (Q1 SP1) we will make sure that even in these cases, the document exports correctly, even if some images are missing.
Best wishes,Iva
