RadTreeView provides support for RTL languages.

RadTreeView considers the direction attribute set to the control itself or any parent HTML element. If you set the direction of the body tag (or any other parent element that contains the control) to rtl, RadTreeView reverses the node order and aligns itself to the right side of the container.
