# TrackBar

The Wisej.NET `TrackBar` is a scrollable control similar to the `ScrollBar`. Configure value ranges by setting the `Minimum` property for the lower end and the `Maximum` property for the upper end.

The `LargeChange` property defines the increment to add or subtract from the `Value` property when clicking either side of the scroll box. The track bar displays horizontally or vertically.

Use this control to input numeric data through the `Value` property, which can be displayed in a control or used in code.
