TrackBar Control Overview (Windows Forms)
The Windows Forms xref:System.Windows.Forms.TrackBar control (also sometimes called a "slider" control) is used for navigating through a large amount of information or for visually adjusting a numeric setting. The xref:System.Windows.Forms.TrackBar control has two parts: the thumb, also known as a slider, and the tick marks. The thumb is the part that can be adjusted. Its position corresponds to the xref:System.Windows.Forms.TrackBar.Value%2A property. The tick marks are visual indicators that are spaced at regular intervals. The trackbar moves in increments that you specify and can be aligned horizontally or vertically. For example, you might use the track bar to control the cursor blink rate or mouse speed for a system.
Key Properties
The key properties of the xref:System.Windows.Forms.TrackBar control are xref:System.Windows.Forms.TrackBar.Value%2A, xref:System.Windows.Forms.TrackBar.TickFrequency%2A, xref:System.Windows.Forms.TrackBar.Minimum%2A, and xref:System.Windows.Forms.TrackBar.Maximum%2A. xref:System.Windows.Forms.TrackBar.TickFrequency%2A is the spacing of the ticks. xref:System.Windows.Forms.TrackBar.Minimum%2A and xref:System.Windows.Forms.TrackBar.Maximum%2A are the smallest and largest values that can be represented on the track bar.
Two other important properties are xref:System.Windows.Forms.TrackBar.SmallChange%2A and xref:System.Windows.Forms.TrackBar.LargeChange%2A. The value of the xref:System.Windows.Forms.TrackBar.SmallChange%2A property is the number of positions the thumb moves in response to having the LEFT or RIGHT ARROW key pressed. The value of the xref:System.Windows.Forms.TrackBar.LargeChange%2A property is the number of positions the thumb moves in response to having the PAGE UP or PAGE DOWN key pressed, or in response to mouse clicks on the track bar on either side of the thumb.
