  Hi,
  
  I am trying to implement the drag and drop functionality between the RadScheduleView and listbox. I have followed the samples provided by telerik to implement the task. I have a converter named "ScheduleViewToAppointmentConverter" and also ScheduleVIewDragDropBehaviour class to implement the cusotom drag drop behaviour. In the Beaviour class i have override the Drop method and add it to the destination source . The code snippet for the behaviour class is as follow . Here eventhogh i get the dragged data in the drop menthod i coudnt communicate with the view model.
  
  

  public class ScheduleViewDragDropBehavior : Telerik.Windows.Controls.ScheduleViewDragDropBehavior

     {

         public override IEnumerable<IOccurrence> ConvertDraggedData(object data)

         {

             if (DataObjectHelper.GetDataPresent(data, typeof(Deal), false))

             {

                 return ((IEnumerable)DataObjectHelper.GetData(data, typeof(Deal), false)).OfType<IOccurrence>();

             }

             return base.ConvertDraggedData(data);

         }

   

   

         public override void Drop(Telerik.Windows.Controls.DragDropState state)

         {

             if (state.SourceAppointmentsSource == state.DestinationAppointmentsSource)

             {

                 base.Drop(state);

             }

             else

             {

                 var appointmentToAdd = state.Appointment as Deal;

                 appointmentToAdd.Subject = "Boney";

                 appointmentToAdd.Start = state.DestinationSlots.First().Start;

                 appointmentToAdd.End = state.DestinationSlots.First().End;

                 (state.DestinationAppointmentsSource as ObservableCollection<Deal>).Add(appointmentToAdd);

             }

         }

          

     }

  
  Here deal is the custom appointment class.
  
  Now i want to implement the drag and drop through commands, so that i can get the dragged data in the view model itself and hence i can add it the itemsource for the schedule view and i am planning to implement the validations too. How can i implement the drag and drop though commands. Any suggestions please.
  
  
  An help will be greatly appreciated.
  
  Thanks in advance.
