RadDomainUpDown
Represents a spin control that displays a collection of text values through which users can navigate using up and down buttons. The RadDomainUpDown class is essentially a wrapper for the RadDomainUpDownElement. All UI and logic functionality is implemented by the RadDomainUpDownElement class, while RadDomainUpDown acts to transfer events to and from its RadDomainUpDownElement instance.
