You could subscribe for the CollectionChanged event of the Appointments collection of the scheduler:
In this event you could check the action state and if it is an Add state do the changes that you want:
sender, Telerik.WinControls.Data.NotifyCollectionChangedEventArgs e)
(e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Add)
//Add your code here
