Property Value

Type: Integer

 

When the user presses the PAGE UP or PAGE DOWN key or clicks the track bar on either side of the scroll box, the Value property changes according to the value set in the LargeChange property. You might consider setting the LargeChange value to a percentage of the Height (for a vertically oriented track bar) or Width (for a horizontally oriented track bar) value. This keeps the distance your track bar moves proportionate to its size.
