Remarks

You do not typically use the ScrollableControl class directly. The ContainerControl and Panel classes inherit from this class.

The ScrollableControl class acts as a base class for controls that require the ability to scroll. To enable a control to display scroll bars as needed, set the AutoScroll property to true and set the AutoScrollMinSize property to the desired size. When the control is sized smaller than the specified minimum size, or a child control is located outside the bounds of the control, the appropriate scroll bars are displayed.

To manually override which scroll bars are visible, set the VScroll and HScroll properties. If either property is set to false, the corresponding scroll bar is not visible, even if the AutoScroll property is set to true.

You can handle the Scroll event to know when the user or code scrolls the client area.

When adding controls programmatically to a form, use the AutoScrollPosition property to position the control either inside or outside of the current viewable scroll area.
