Hi Marco,

There's an internal constructor that can be used to make the collection raise events, so you could use it if you have the source code. Otherwise we'll make it public for the next release.

Actually you can use for this purpose the ObservableCollection generic class from the System.Collections.ObjectModel namespace. Create an ObservableCollection<DiagramNode> instance and handle its CollectionChanged event. The Action event argument specifies whether an item is added to or removed from the collection.

I hope that helps,
Stoyan
