Change default appointment duration

[Andrey]

Hello!

In my application I have a ListBox and RadScheduleView. I can create a new appointment by drag'n'drop from ListBox. Default duration for new appointment is 1 hour.

I have a  ScheduleViewDragDropBehavior class and I tried to set End property for new appoinment here, but Start and End properties are equal 1000/01/01. 

public class ScheduleViewDragDropBehavior : Telerik.Windows.Controls.ScheduleViewDragDropBehavior
    {
        public override IEnumerable<IOccurrence> ConvertDraggedData(object data)
        {
            if (DataObjectHelper.GetDataPresent(data, typeof(Campaign), false))
            {
                var campaigns = DataObjectHelper.GetData(data, typeof(Campaign), true) as IEnumerable;
                if (campaigns != null)
                {
                    var appCollection = campaigns.OfType<Campaign>().Select(c => new AppointmentCampaign { Subject = c.Name, Campaign = c, Category = new Category("", c.Brush) });

                    return appCollection;
                }
            }
            return base.ConvertDraggedData(data);
        }
    }

 

So, how can I change default duration?

Hello Andrey,

You should override CanDrop method in your ScheduleViewDragDropBehavior and change the End time of the destination slot. Here is an example:

public override bool CanDrop(Telerik.Windows.Controls.DragDropState state)
{
    var destSlot = state.DestinationSlots.First();
    destSlot.End = destSlot.Start.AddHours(2);
    return base.CanDrop(state);
}

Hi Andrey,

Actually it should be like this:

public override bool CanDrop(Telerik.Windows.Controls.DragDropState state)
{
    if (state.DestinationAppointmentsSource != state.SourceAppointmentsSource)
    {
        var destSlot = state.DestinationSlots.First();
        destSlot.End = destSlot.Start.AddHours(2);
    }
    return base.CanDrop(state);
}

The condition is needed to distinguish whether the appointment is dragged from outside the ScheduleView.

All the best,
