If you are using Windows scroll bars, just use the GetScrollBarInfo() Win32 API to get information about different parts of the scroll bar.
In the case of CExtScrollBar or CExtZoomScrollBar, you can use the following code: CExtScrollBar * pScrollBar = . . .
CExtPaintManager::PAINTSCROLLBARDATA _psbd( pScrollBar ); The CExtPaintManager::PAINTSCROLLBARDATA class has several CRect members describing the location and size of scroll bar’s parts.

You should override CExtScrollItemWnd::OnSwGetLineSize method (CExtGridWnd is derived from CExtScrollItemWnd class, so overriding is possible). Check out default implementation and change it as you need in your overriden method.
