The ConnectorPointType event's property returns whether the connection point that is about to be changed is the begin or end point. To get the previous diagram item and its connection point to which the connection point was glued, use the OldItem and OldIndex properties correspondingly. The new item and its connection point are returned by the NewItem and NewIndex properties.

The ConnectionChanged event does not occur when a connector is being added or removed.
