Change color on the TAdvStringGrid scrollbar?

Can I change the color of the TAdvStringGrid scrollbar? I found this:

  if Message.ChildWnd = ScrollBar1.Handle then
   Message.Result := CreateSolidBrush(RGB(255, 255, 0));

but it only works if I can get the handle of the scrollbar and it appears to be private.


The scrollbars used in TAdvStringGrid are not standalone scrollbars and as such have no handle. The scrollbars are just part of the scrolling window control in which TAdvStringGrid is hosted, so there is the handle of this scrolling window control but not separate handles of scrollbars.
