Sorting through RadGridView

If you bind RadGridView.ItemsSource to RadDataServiceDataSource.DataView, you will get automatic server-side sorting. When the user defines his sorting criteria through RadGridView’s UI, RadGridView will automatically transfer the resulting SortDescriptors to RadDataServiceDataSource. If RadDataServiceDataSource.AutoLoad is true, the control will automatically go to the server and get the ordered data.

If AutoLoad is false, the descriptors will be transferred to RadDataServiceDataSource, but no trip to the server will be made until the Load method is called.
