Yudi,

I have your cust example working just fine.  Yes, Intersoft controls work great with ObservableCollection.  That is NOT the problem.

I have a DataView object, which is also IEnumerable and works fine with other control bindings, just not intersoft.  WHY WHY WHY??  According to the documentation, if its IEnumerable, it should work, BUT it does NOT work. WHY?

I am using an Access Db as local db.  I am using Visual Studio Data Source Designer to bring in all the data model and hibernate all the needed interface.  Why would I want to manually create all my data models using ModelBase.cs and create all new ViewModel functions using ObservableCollection??? 

This would take a lot of time and effort. Yes!!!

The problem remains, Intersoft does NOT bind to DataView or CollectionViewSource objects.  Most everything on the PLANT EARTH DOES.

Yes I know this must be a bug.  If you simply acknowlegde this as a bug and let me know of any workarounds and tell me you all are working on a solution and it will be out in some hotfix or release, you will make me happier.
