I was looking at the demo: Telerik's Demo and this Telerik's Example
I still cannot figure out how, using this technique, to pass a parameter to the Read method, so instead of reading ALL games or products, it reads ONLY a subset of games or products, by category ID lest say. If I change the Read method in the server-side code to take a parameter, it never gets hit anymore, and I cannot figure out how to pass a parameter from the transport client-side definition definition... Any help would be highly appreciated!
I posted the question to the Telerik's forums and got this which should work! Telerik's Answer
