RadSplitter allows you to define minimum and maximum size to which a pane can be
resized. Use the MinWidth, MaxWidth and MinHeight,
MaxHeight properties of the RadPane object to set these restrictions.
You can disable the scrollbars of a pane by setting Scrolling property
of the RadPane to none.
Instructions
