You can set the scroll bar appearance, height, width, and visibility.
You can hide or show the vertical or horizontal scroll bar. You can also set the width of the vertical scroll bar and the height of the horizontal scroll bar.
You can use the thumb bar (drag button) to scroll large areas of the control. Use the button with the arrow to scroll a row or column at a time. You can also specify whether to scroll after releasing the mouse with the ScrollBarTrackPolicy property.
The control scrolls by default when selecting and dragging headers or cells outside of the current visible area.
Using Code
The following example sets properties for the scroll bar.
