Hi,

I'm currently looking at using RadGridView with Data Virtualizing, fetching data via RIA Services.

My return type is not a mapped entity though, as I'd like to join multiple tables and via projection return a list of objects which are ComplexTypes.

I got this working with data virtualizing, but I have no idea how I can add support for column filtering and sorting with this method.

Any tips are highly appreciated.

Update:
I finally figured out how to map a database view with Entity Framework (Code First), and that made it much simpler to achieve my goal here. Problem solved.
