The event handler receives an argument of type AnnAfterObjectChangedEventArgs containing data related to this event. The following AnnAfterObjectChangedEventArgs properties provide information specific to this event.

Property	Description
ChangeType	Gets the type of change.
Designer	Gets the designer responsible for the change.
