Thank you for your interest in Telerik products.
I'm afraid this scenario is not supported. When you use LoadWith() of the fetch strategy, you are actually indicating which member should be loaded together with the entity from the generic parameter. It does not indicate the actual data that is loaded. A predicate in this case is not supported.
However, you can workaround this limitation by creating a SQL Server view that loads filtered data and map an entity to this view. Then you can use the fetch strategy in the same manner as when you are using table. Have in mind that Telerik DataAccess ORM requires entiites to have primary key but you cannot define primary key for views. Have a look at this article
for information how to solve this issue.
I hope this information is helpful.
OpenAccess ORM is now Telerik Data Access
