while we move one appointment, it may overlap other one, instead of overlapping we need to move that also synchronised with initial one. is this feature available in  schedule view?

Hello Rajesh,

RadScheduleView doesn't support such functionality out of the box.   You can try to implement it with a custom DragDropBehavior. More information about it can be found here.

You can find the existing appointments in Drop method like this:

public override void Drop(Telerik.Windows.Controls.DragDropState state)
{
    var res = state.DestinationSlots.SelectMany(sl => state.DestinationAppointmentsSource
                .OfType<IAppointment>()
                .Where(a => this.AreOverlapping(a, sl) && !state.DraggedAppointments.Contains(a)));
    base.Drop(state);
}

and AreOverlapping and AreIntersected methods are defined like this:

private static bool AreIntersected(IEnumerable<IResource> first, IEnumerable<IResource> other)
{
    IEnumerable<IResource> firstResources = first
        .Distinct();
 
    IEnumerable<IResource> otherResources = other
        .Distinct();
 
    return firstResources.Where((IResource r) => otherResources.Contains(r)).Count() == firstResources.Count();
}
 
private bool AreOverlapping(IAppointment appointment, Slot slot)
{
    return appointment.IntersectsWith(slot) && AreIntersected(appointment.Resources.OfType<IResource>(), slot.Resources.OfType<IResource>());
 
}

Please try it and if you have any difficulties, write to us again.
