RAD Studio
Up-down Controls (VCL Only)

In VCL applications only, an up-down control (TUpDown) consists of a pair of arrow buttons that allow users to change an integer value in fixed increments. The current value is given by the Position property; the increment, which defaults to 1, is specified by the Increment property. Use the Associate property to attach another component (such as an edit control) to the up-down control.
