This method clears the Collection Source’s collection, disposes of the resources allocated by the collection and recreates it. The ResetCollection method raises two events - CollectionSourceBase.CollectionChanging and CollectionSourceBase.CollectionChanged. Handle them to be notified when a collection is recreated.

Generally you do not need to call this method, it is called automatically by XAF in certain situations. For instance, when a Detail View contains a nested List View and the Detail View’s ViewItem.CurrentObject changes, XAF calls this method to recreate the nested List View’s Collection Source’s collection.
