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:</SPAN><BR /><BR /><SPAN>ArcMap.Document.UpdateContents();</SPAN><BR /><BR /><SPAN>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.</SPAN><BR /><BR /><SPAN>Is this the correct method to use?</SPAN><BR /><BR /><SPAN>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:</SPAN><BR /><SPAN>"Notifies the document that the contents have been updated."</SPAN><BR /><SPAN>"Refreshes the current view in the table of contents. UpdateContents is a shortcut - it calls Refresh on the current contents view (IContentsView::Refresh)."</SPAN><BR /><BR /><SPAN>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.</SPAN><BR /><BR /><SPAN>-Jeff</SPAN></BODY></HTML> Tue, 16 Nov 2010 21:17:02 GMT https://community.esri.com/t5/arcobjects-sdk-questions/notifying-arcmap-document-to-save-persistent-data/m-p/9637#M236 JeffreyHamblin 2010-11-16T21:17:02Z Re: Notifying ArcMap document to save persistent data for Add-in https://community.esri.com/t5/arcobjects-sdk-questions/notifying-arcmap-document-to-save-persistent-data/m-p/9638#M237 <HTML><HEAD></HEAD><BODY><SPAN>You need to set the document save flag by calling IDocumentDirty2.SetDirty.</SPAN></BODY></HTML> Wed, 17 Nov 2010 13:11:18 GMT https://community.esri.com/t5/arcobjects-sdk-questions/notifying-arcmap-document-to-save-persistent-data/m-p/9638#M237 NeilClemmons 2010-11-17T13:11:18Z Re: Notifying ArcMap document to save persistent data for Add-in https://community.esri.com/t5/arcobjects-sdk-questions/notifying-arcmap-document-to-save-persistent-data/m-p/9639#M238 <HTML><HEAD></HEAD><BODY><SPAN>Thank you for the information, Neil.
