I have been able to get the save function working to post to another page, but this does not suit my needs as I am expected to be able to click on a save button that would do a post back so that all the controls on the page are saved, not just the diagram. Additionally, it would be nice to be able to associate individual pieces of the diagram to entities in the database, but for now, I would just like to know how to include the diagram as part of a page post that I am able to get all the controls on the page, not just the diagram.
