RadPropertyGrid ScrollPattern methods and properties not working as expected.

Hi, 

         I have used Scroll Pattern on RadPropertyGrid to get VerticalScroll Percent but the value is '0.0' only even after the scroll happened till end.

 Another problem is  with Scrollpattern.ScrollVertical(ScrollAmount.LargeIncrement) method .It is doing smallincrements instead of PageDown or PageUp and vice versa.

Regards,

Nagasree.
