QuestionQuestion about NotifyCollectionChangedEventArgs Pin
Super Lloyd1-Mar-22 12:12
MemberSuper Lloyd1-Mar-22 12:12 
The idea with a collection that implements INotifyCollectionChanged, is that it will be (possibly) be used in an ItemsControl, which will get the CollectionViewSource.GetDefaultView(Object) for it, that is likely to be a ListCollectionView.

So far... so good...

However, as I just discovered today Blush | :O OMG | :OMG: , when using AddRange(), RemoveRange(), i.e. creating Add/Remove events with more that 1 object will trigger the following error in the ListCollectionView:
System.NotSupportedException: Range actions are not supported.

Stack Trace: 
ListCollectionView.ValidateCollectionChangedEventArgs(NotifyCollectionChangedEventArgs e)
ListCollectionView.ProcessCollectionChanged(NotifyCollectionChangedEventArgs args)
AbstractInvocation.Proceed()
Invocation.CallBase() line 147
ReturnBaseOrDefaultValue.Execute(Invocation invocation) line 88
IInterceptor.Intercept(Invocation invocation) line 34
Interceptor.Intercept(IInvocation underlying) line 113
AbstractInvocation.Proceed()
NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e)

Mmm... unfortunate... Cry | :((

I can think of 2 possible fixes and I am undecided as to which one to use?!
  1. When a range Add/Remove event if fired, instead fire a Reset event.
  2. When a range Add/Remove event if fired, instead fire multiple Add/Remove single item events.
  3. or.. mmm... have a FireEventMode property, which would let the user decide whether to use event as is, split it, or fire Reset.
Wo.. what say you?
