RadScrollBar
Implements the basic functionality for the scrolling.
This class can be used both for horizontal and for vertical scrolling through its property ScrollType. Only the specialized children are put in the Toolbox: RadHScrollBar and RadVScrollBar.
To adjust the value range of the scroll bar control set the Minimum and Maximum properties. To adjust the distance the scroll thumb moves, set the SmallChange and LargeChange properties. To adjust the starting point of the scroll thumb, set the Value property when the control is initially displayed.
