As you move through the collection of items in the System.Windows.Forms.DomainUpDown control using the down button, you will eventually reach the last item in the collection. If you continue, and DomainUpDown.Wrap is set to true, the list will start over with the first item in the collection and appear to be continuous. This behavior also occurs when you move through the collection using the up button.
