[Solved] Drag and drop from rad grid view to scheduler

[bonDaviD]

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.
