.NET Windows Forms in a Nutshell

Name

TrackBar

Synopsis

This Control represents a horizontal or vertical slider control, similar to a ScrollBar in function. The Orientation property determines whether the control will offer the horizontal or vertical imagery. You can also specify whether tickmarks appear with the TickStyle and TickFrequency properties.

It has further properties that define the Minimum and Maximum values for the range (SetRange() also allows you to do this), and you can get or set the current Value.

The SmallChange property determines the value to be added or subtracted when the arrow keys are pressed. Similarly, the LargeChange property determines the value to be added or subtracted when the slider body is clicked (or the page up/down keys are pressed).

As the Value is changed, the control raises the ValueChanged event. When the slider moves, it raises a Scroll event (this is much simpler than the ScrollBar equivalent).
