RadTabStrip provides support for RTL languages.
RadTabStrip 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, RadTabStrip reverses the
tab order and aligns itself to the right side of the container.
