Will said form still show up since the default forms aren't being used? And if it doesn't is there any way to get it to?
No. You will want to handle the ConcurrencyException event on the BO itself. This is where all of the concurrency exceptions that are bubbled up to the form come from anyway. You can then display your own form and display the information to the end-user as you please...or just handle the exception and manually manage the collision. If you look at the EventArgs of the Concurrency Exception, it gives you everything that you need including the local and server values, etc. You then set which value you want to accept for each item within the collection and it will then process your request.
