Hello I have an annoying edit level mis-match error.

I have a List of Parents which is bound to a datagrid and I am trying to assign a Child object selected from a List of Child objects.

When I do the assignation, it eventually calls the ResetChildEditLevel but assigns the same edit level as that of the parent's which causes an edit level mis-match in AcceptChanges().

I wasn't sure if I was suppose to enter in that thread since my situation is slightly different. Also the solutions posted in that thread didn't solve my problem.

To specify I tried using the .Clone() method.

But its the same issue. The edit levels don't match due to databinding, and when you clone it still keeps the same edit level values as the original.

When you assign the Child to the new Parent through SetProperty() it rebinds the Child to the new Parent and then calls ResetChildEditLevel() which resets the EditLevel to the new Parent. At least that's what the book states, and my traces confirm it. So I'm wondering how it goes back to the original values as you stated. I'm clearly missing something.

But you're doing this all while databound, correct? You can't do things "behind databinding's back," so to speak.

So you can't clone an object that is databound? Why would that be?
