This article describes the inner structure and organization of the elements which build the RadDomainUpDown control.

RadDomainUpDown is a derivative of a RadDropDownList. Unlike RadDropDownList, RadDomainUpDown doesn't show a popup with the items:

    2. RadSpinElementDownButton - a button element that moves to the next item in the list.
