I have a requirement to put a large amount of data into a Kendo UI grid and want to have the best performance possible. I reviewed the Virtualization of Remote Data example at http://demos.telerik.com/kendo-ui/grid/virtualization-remote-data . What are the specs/requirements for the server-side service that will provide the data to be consumed by the grid? I only see sample client-side code(JavaScript). Please advise, thanks.
