Drag-drop between ListBox and ScheduleView

To enable drag-drop between a ListBox and a RadScheduleView, on the ListBox should be attached a ListBoxDragDropBehavior and a DataConverter. The DataConverter should convert the dragged items from the ListBox into a ScheduleViewDragDropPayload and vice versa.

Following is an example demonstrating how to convert appointments between a ListBox and a ScheduleView:

• Create the DataConverter:

  C#

  	public class ScheduleViewToAppointmentConverter : DataConverter
  	{		
  		public override string[] GetConvertToFormats()
  		{
  			return new string[] { typeof(ScheduleViewDragDropPayload).FullName};
  		}
  	
  		public override object ConvertTo(object data, string format)
  		{
  				
  			if (format == typeof(ScheduleViewDragDropPayload).FullName && DataObjectHelper.GetDataPresent(data, typeof(Appointment), false))
  			{
  				var appointments = (IEnumerable)DataObjectHelper.GetData(data, typeof(Appointment), false);
  				if (appointments != null)
  				{
  					return new ScheduleViewDragDropPayload(null, appointments.OfType<IOccurrence>().ToList());
  				}
  			}			
  			return null;
  		}
  	}

• Add CustomScheduleViewDragDropBehavior class which inherits ScheduleViewDragDropBehavior:

  C#

  	public class CustomScheduleViewDragDropBehavior : ScheduleViewDragDropBehavior
  	{
  		public override IEnumerable<IOccurrence> ConvertDraggedData(object data)
  		{
  			if (DataObjectHelper.GetDataPresent(data, typeof(Appointment), false))
  			{
  				var appointments = DataObjectHelper.GetData(data, typeof(Appointment), true) as IEnumerable;
  				if (appointments != null)
  				{
  					return appointments.OfType<IOccurrence>();
  				}
  			}
  	
  			return base.ConvertDraggedData(data);
  		}
  	}

• The final configuration of the two controls in XAML should look like:

  XAML

  	<telerik:RadScheduleView ...>
  		<telerik:RadScheduleView.ViewDefinitions>
  			<telerik:WeekViewDefinition />
  		</telerik:RadScheduleView.ViewDefinitions>
  		<telerik:RadScheduleView.DragDropBehavior>
  			<local:CustomScheduleViewDragDropBehavior />
  		</telerik:RadScheduleView.DragDropBehavior>
  	</telerik:RadScheduleView>
  	
  	<ListBox ...>
  		<drag:ListBoxDragDrop.DataConverter>
  			<local:ScheduleViewToAppointmentConverter />
  		</drag:ListBoxDragDrop.DataConverter>
  		<drag:ListBoxDragDrop.Behavior>
  			<drag:ListBoxDragDropBehavior />
  		</drag:ListBoxDragDrop.Behavior>	
  	</ListBox>

Here is the result:
