# WinForms DomainUpDown Overview

**RadDomainUpDown** is a combination of a text-box and a pair of moving up and down arrow buttons to navigate through a predefined list of items. The control displays a text from a list of string available options. By clicking the up or down arrow button, the user can navigate backward or forward in the items list.

* Unbound mode - adding the items manually via code.
