You are right that there is no event that is fired when the ItemsSource
is changed. Please note that this property should be used in data binding scenarios and this property should be bound to a property from your ViewModel
. Hence you know when you add items to your business collection and no event is needed to inform you for the change (as you do that change).
On the other hand you can invoke a custom event (if you still need one) when you add an item.
