I'm working on an Add-in (using C#) that needs to store some information in the MXD. I got that working successfully using the concepts outlined in the "Persisting data by implementing an extension using add-ins" topic in the SDK Help. However, unless the user saves the document, the changes aren't written (of course). Looking for a way to notify ArcMap that the document needs to be saved, the only thing I could find that works is calling:
ArcMap.Document.UpdateContents();
once for each document session if the data I am storing changes. If I do that, then ArcMap will prompt the user to save if necessary when closing the document -- which is exactly what I want.
Is this the correct method to use?
This was kind of a guess, since I could not find any other posts or samples about this subject. The documentation for the UpdateContents() method only states:
"Notifies the document that the contents have been updated."
"Refreshes the current view in the table of contents. UpdateContents is a shortcut - it calls Refresh on the current contents view (IContentsView::Refresh)."
It was enough to give it a try, but it would be nice if the documentation was more explicit about it producing a "save" prompt.
