In 2009.1 and later, handle AppointmentsDragging and cancel it

I had to disable appointment draggin from one owner to another, and this helped:

    Private Sub ultraDayView1_AppointmentsDragging(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinSchedule.AppointmentsDraggingEventArgs) Handles ultraDayView1.AppointmentsDragging

        e.AllowOwnerChange = False

    End Sub
