Public Property LargeChange As Integer

Property Value

Type	Default	Description
Int32	10	An integer value representing the increment applied when the scroll box is moved by a ‘page’.

Remarks

Scroll bars provide easy navigation through a long list of items or a large amount of information by scrolling horizontally and/or vertically within an application or control. When a user presses the PAGE UP or PAGE DOWN key or clicks in the scroll bar track on either side of the scroll box, the ScrollBarBase.Value property changes according to the LargeChange value.

Use the ScrollBarBase.SmallChange property to determine the increment applied when the user presses one of the keyboard arrow keys or clicks one of the scroll-bar buttons.

The ScrollBarBase.Scroll and ScrollBarBase.ValueChanged events fire each time the scroll box has been moved by a mouse or keyboard action.
