Rad Scheduler: Drag and Drop: modified appointment has unchanged value

[rjb227s]

Hello,

I am having this same issue and the solution below was unfortunately not a helpful answer.  I have spent so many hours on this I have lost count. 

When dragging and dropping an appointment, the AppointmentUpdate Server event has the same value for the event args for the e.Appointment AND e.ModifiedAppointment.  When I add the client event OnClientAppointmentMoveEnd, I get the correct modified value on the client side, but the serverside is always wrong.

[.net 2.0 + Q3 2009 with hotfix]

Thanks for the help,

Ryan (Code Below)

Server Code: (values for e.Appointment and e.ModifiedAppointment are the same)

protected void CalendarRadScheduler_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
        {
            if (e.Appointment.Start != e.ModifiedAppointment.Start)
            {
                Appointment objModApt = e.ModifiedAppointment;

                //load message from database
                MessageDAO daoMessage = new MessageDAO();
                MessageDTO dtoMessage = daoMessage.GetById((int)objModApt.ID);

                //update message with new time
                dtoMessage.Start = objModApt.Start;
                dtoMessage.End = objModApt.Start.AddMinutes(10);

                //Save updated message to database
                dtoMessage.Method = CoreToolkit.ObjectMethod.Modify;
                daoMessage.Save(dtoMessage);
            }
            else
            {
                e.Cancel = true;
            }
        }
