Indeed, Telerik Data Access does not currently support scenarios where a relation is defined between a Foreign Key and a Unique column. Adding support for such scenarios would be a completely new feature of the product. Therefore we have an existing feature request
about this functionality. We would like to invite you to vote for it at our Feedback Portal
. Doing so will help us prioritize its eventual implementation.
I hope this helps. Should you have additional questions, feel free to post at our forums again.
OpenAccess ORM is now Telerik Data Access
. For more information on the new names, please, check out the Telerik Product Map
