.NET Windows Forms in a Nutshell

Name

DomainUpDown

Synopsis

This Control allows you to specify a list of Items from which you can select—similar to a ListBox or ComboBox, except only a single item is displayed at any one time, and there are up-down spin buttons to enable selection from that list. You can retrieve the SelectedIndex or SelectedItem.

This control is extremely difficult to use, and you should always consider using a ComboBox instead, unless there is really no room on your display for the drop list (e.g., you have a 320 × 100 LCD) .
