The example below illustrates how to override the AllowAppointmentConflicts property that is set to false.

C#

private void Scheduler_DropAppointment(object sender, DropAppointmentEventArgs e) {
    for (int i = 0; i < e.DragAppointments.Count; i++) {
        //if a dragged appointment does not intersect another appointment
        if (e.ConflictedAppointments[i].Count == 0) {
            //it can be moved to the desired position
            e.SourceAppointments[i].Start = e.DragAppointments[i].Start;
            e.SourceAppointments[i].End = e.DragAppointments[i].End;
    }
}

VB.NET

 Private Sub Scheduler_DropAppointment(ByVal sender As Object, ByVal e As DropAppointmentEventArgs)
    For i As Integer = 0 To e.DragAppointments.Count - 1
        'if a dragged appointment does not intersect another appointment
        If e.ConflictedAppointments(i).Count = 0 Then
            'it can be moved to the desired position
            e.SourceAppointments(i).Start = e.DragAppointments(i).Start
            e.SourceAppointments(i).End = e.DragAppointments(i).End
        End If
    Next i
