Hi Serdar,
As far as I see, you create a dataAdapter before your binding is completed. Please, refer to the help topic to learn how to bind the widget to any of the supported data sources. The dataAdapter should handle your Ajax requests and the Grid should be bound to a dataAdapter. If you wish to use your way, then create the dataAdapter after your jQuery Ajax function call is completed and then set the Grid’s source property to point to the dataAdapter.
