We would like a new SetDirtyOnAdd property that works just like the SetDirtyOnEdit property for business objects.  If a user clicks to add a record and never actually enters any data, when they close the screen we don't want to show the save changes confirmation message.  Is this possible?

Is there something else I can look at on the BO to determine if the current row is truly dirty? I don't want to ask the user to save changes on exiting a form if they have not changed anything. The IsDirtyOnEdit property works great for editing, but I need to do the same type of thing for adding.

Why can't you just look at the row state?  This will tell you what is going on with the current row.
