Using the following class to manage data conversion between a scheduleview and listbox:

using Telerik.Windows.Controls.ScheduleView;
using Telerik.Windows.DragDrop.Behaviors;
 
namespace DragDrop
{
    public class AppointmentConverter : DataConverter
    {
        /// <summary>
        /// Returns a list of all formats that the data in this data object can be converted to.
        /// </summary>
        public override string[] GetConvertToFormats()
        {
            string assemblyName = typeof(Appointment).AssemblyQualifiedName;
            return new string[] { assemblyName };
        }
 
        /// <summary>
        /// Retrieves a data object in a specified format; the data format is specified by a string.
        /// </summary>
        public override object ConvertTo(object data, string format)
        {
            if (DataObjectHelper.GetDataPresent(data, typeof(ScheduleViewDragDropPayload), false))
            {
                ScheduleViewDragDropPayload payload = (ScheduleViewDragDropPayload)DataObjectHelper.GetData(data, typeof(ScheduleViewDragDropPayload), false);
 
                if (payload != null)
                {
                    return payload.DraggedAppointments;
                }
            }
            return null;
        }
    }
}

I cannot drag a CustomAppointment (as coded in the Telerik Demo)
back to a list box from a schedule view. No exception or error,
it just simply doesn't let me (cursor icon changes to a 'not
permitted' icon).

Hi Daniel,

Please find attached an example which demonstrates how you can implement  drag and drop between RadScheduleView and ListBox.

Hope it helps.

All the best,

Yana, thanks a lot for your solution. It does as I had requested - one thing I have noted though is that in my solution, I can touch down and drag an item from the listbox, but this touch functionality doesn't seem to work with the listbox you have used in your project.

I have made sure both of our list box's data templates and drag drop behaviours are the same so I'm pretty stuck on this now. One of the differences I have noted is the converter class. Any ideas??

Thanks again.
