This is the abstract base class for the HScrollBar and the VScrollBar controls.

It has properties that define the Minimum and Maximum values for the scrollbar, and you can get or set the current Value.

The SmallChange property determines the value to be added or subtracted when the buttons are clicked (or 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 scrollbox moves, it raises a Scroll event. Note that if you drag the slider knob, you get a Scroll when the mouse button is first depressed (with ScrollEventArgs.NewValue = = Value). As the mouse moves, you get a Scroll before the Value has been updated, then a ValueChanged event as the Value is updated. Finally, you get another Scroll as the mouse is released (with ScrollEventArgs.NewValue = = Value).
