Hello Randy Minder,
If we understood you right, by Referential Integrity you mean keeping the object graph in a consistent state. This is achievable by using the
[Telerik.OpenAccess.Depend()] attribute. You can place it on the Territory property of the Customer class. That way, whenever you delete a Customer object, its related Territory will be deleted as well. If you had different idea in mind, please provide us with some more information so we can give you concrete answer for your specific scenario.
Best wishes,
Zoran
the Telerik team
