Hello

Below I have listed the method to reproduce the problem.
Open the Telerik WPF Controls Examples > ScheduleView > Features > Configurator.
Check "Snap Appointments" and set "Day Start Time" to for example 08:00.
Start dragging an appointment to start time 08:00, nothing strange will happen, when you now drag the appointment a little bit higher (so the start time will be earlier) the appointment disappears.

I assume this is a bug?
Can you help on this? (maybe a workaround?)

Thanks!

Hi Labarque,

We are aware of the explained issue and it has already been logged in our internal backlog. I also logged it in our Feedback portal so you can easily track its status on the following link:
http://feedback.telerik.com/Project/143/Feedback/Details/98524-if-snapappointments-is-enabled-and-daystarttime-is-set-when-the-appointment-is-d

However as workaround you can implement a custom ScheduleView DragDropBehavior and override the CanDrop method the following way:

public override bool CanDrop(DragDropState state)
{
    var scheduleView = state.ServiceProvider.GetService<IDialogProvider>() as RadScheduleView;
    var destinationSlot = state.DestinationSlots.First();
    if (destinationSlot.Start.Hour < scheduleView.ActiveViewDefinition.DayStartTime.Hours)
        return false;
    return base.CanDrop(state);
}

Note that this will only work for DayViewDefinition, you can improve the implementation as per your requirements.

Hope this will work for you.

Regards,
Kalin
