class

This Control allows you to specify a list of Items from which you can selectsimilar 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 x 100 LCD) .
