RadListBox provides support for RTL languages.
    
    
        RadListBox 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, RadListBox reverses the item
        order and aligns itself to the right side of the container. However, if you need
        to change the direction of the transfer buttons as well you will need to include
        the following settings to the RadListBox control:
    
    <telerik:ListBox ID="ListBox1" runat="server" dir="rtl"> or simply an outer
    div with 
dir="rtl" as implemented in the demo
    
    
    <ButtonSettings AreaWidth="100px" Position="Left" />
