Custom datasource method not seen

I created a custom datasource method in a new file called MyContextService.Custom.cs extending the public partial class MyContextService. I can use this new datasource method through VS but Radzen cannot see it in the invoke datasource method dropdown for the page load.

How do I make this new method visible to Radzen?

This isn't supported at the moment. Radzen sees only methods generated from database objects. You can use custom methods though.

That explains it, thanks! I like the way Radzen gives us partial classes and had hoped this would have worked in this case too. The get method for this table did not have all the includes for the relations which is why I needed to fashion my own. The generated model has the ICollections but not all ICollections make it to the get methods in the context services. Am I doing something wrong or is this by design?
