The following DiagramConnectionChangingEventArgs properties provide information specific to this event.
Property Description

Connector Returns the connector whose beginning/ending item is about to be changed.
ConnectorPointType Returns the type of the connection point which is about to be moved.
NewIndex Returns the index of the connection point on the diagram item to which the connector is about to be attached.
NewItem Returns the diagram item the connector is about to be attached to.
NewPoint Returns the new coordinates of the connection point which is about to be moved.
OldIndex Returns the index of the connection point on the diagram item from which the connector is about to be detached.
OldItem Returns the diagram item from which the connector is about to be detached.
OldPoint Returns the initial coordinates of the connection point which is about to be moved.

Expanded Remarks

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
