Hi,
When you override AddNewCore, is anyone raising the AddingNew event?
The docs say that raising the event allows listens to place a custom object in the collection, but it also seems likely that there may be those that want to listen to the event so that they are aware an item was added?
Should I be raising the event or not?

That event comes from BindingSource, not from the data source object. So your business object should not raise this event, no.

BindingSource? Do you mean BindingList? I'm confused... if I don't call OnAddingNew protected method, the AddingNew event never fires. Should that be the case for Csla objects?

What object raises AddingNew? It is my understanding that
the BindingSource control raises an AddingNew method, not the data source object
(like a BindingList<T>). There's no AddingNew event defined in any of the
data source interfaces like IBindingList (that I'm aware of at
least).

BindingList<T> defines an AddingNew event. The default implemention of AddNewCore will raise this event as well by calling the OnAddingNew( AddingNewEventArgs ) method.

Huh, well there you go then :)
I should think that you'd want to raise that event
then.

implemention of AddNewCore will raise this event as well by calling the
OnAddingNew( AddingNewEventArgs ) method.
