abstract OnSourceCollectionChanged :
e : NotifyCollectionChangedEventArgs -> unit
override OnSourceCollectionChanged :
e : NotifyCollectionChangedEventArgs -> unit Parameters
- e NotifyCollectionChangedEventArgs
- The details of the collection change.
Remarks
The implementation in SelectionNodeBaseT calls
OnItemsAdded(Int32, IList) and OnItemsRemoved(Int32, IList)
in order to calculate how the collection change affects the currently selected items.
It then calls OnIndexesChanged(Int32, Int32) and
OnSelectionRemoved(Int32, Int32, IReadOnlyListT) if necessary, according
to the SelectionNodeBaseTCollectionChangeState returned by those methods.
Override this method and OnSourceCollectionChangeFinished to provide
custom handling of source collection changes.
