Declarative Ria Data and Controls

I'm really loving this declarative approach with silverlight and wpf... (ask me why and I can't tell you ! :-)

Anyway I've just stumbled across a way of managing RiaDataContexts Declaratively
I found it on the Telerik samples.... If you've not looked at these guys controls then check them out!!
