There's no easy way to do this. You might be able to use a CreationFilter to re-arrange the UIElements, though.

This should be a fairly simply CreationFilter. All you would have to do is determine what element contains the scrollbars. I recommend that you get the Infragistics UIElementViewer Utility to help you with this.

Then your CreationFilter  could handle the AfterCreateChildElements for this containing element and you could move the scrollbar element to the left and shift the other elements over to the right by the width of the scrollbar.
