multiple entity edit with asp.net dynamic data

[ste218]

I have an ASP.NET Dynamic Data 4 web app based on the "ASP.NET Dynamic Data Domain Service Web Application" template. A key user requirement is that the user can choose to edit multiple rows and then submit the bulk to the database for updating. The rows would be highlighted according to their underlying object state. For example, "Added" would be green, "Deleted" would be red, and "Modified" would be yellow. I'm not so interested in batch updates as I am in being able to have more than one object in an edit state simultaneously. The user can click a master "Save" button and have all changes sent to the database, or can cancel and have all changes rolled back. As far as I have been able to determine after extensive and frustrating searching, is that this is not a scenario that is possible using Dynamic Data. Has anyone been able to achieve this behaviour and if so, could you please point me in the right direction to figure out how to do it.Thanks, Alex.
