abstract class

This class provides the base functionality for the DomainUpDown and NumericUpDown controls. It offers a text box with an attached spin control.

InterceptArrowKeys determines whether you can use the arrow keys to spin the value up and down. UpDownAlign sets the spin buttons to the left or right of the control, respecting the right-to-left setting of the context. UpButton() and DownButton() programmatically invoke the pressing of the respective spin buttons.
