Hi I'm very happy about this new method that was added in 4.0. It's just I'm not sure I'm using it correctly.
I have a collection of abstract base classes wrapped in a ListCollectionView and wan't to use AddNewItem to instance a derived class when the new button ( or NewItemPlaceholder ) is pressed. Is this the way it was thought of being used as or was it mailny
for people using parameter constructors?
Reason I ask is that CanAddNew item returns false. I guess that's only relevant with AddNew and not AddNewItem.
Also is there any tutorial for using NewItemPlaceholder. how you implement clicking it to add the new item and such. Only think I can think of is templating it as a button. Is there any other more inherit way?
