There are no server methods for appointment start and end drag events but you can use AppoinmentUpdate method that is thrown when the appointment is dropped. If RadScheduler is bound to SqlDAtaSource declaratively all the updates including the ones that occur after drag are saved in the DataBase.
Hope this will be helpful.
