Description

OnDelete is fired if you delete a simple or attributed relationship in one of the following ways:

• Call IRelationshipClass.DeleteRelationship
• Call IRow.Delete on an AttributedRelationship

Note that one can also create and delete relationships implicitly by directly using put_Value to set the origin foreign key field inside the destination object in the case of a simple relationship class.   However, no events in IRelationshipClassEvents will be fired if the user does this (for eg. uses the Table document to directly set foreign key values in the destination object).
