I am trying to create a grid-like control containg a header for column
headings and a body for row data.

To do this I inherit the header and body from ScrollableControl and have
synchronised the scrolling between them such that scrolling the body
horizontally will also scroll the header.

My problem is that I cannot make the hide scrollbars on the header control.
Setting the HScroll and VScroll properties appears to have no effect.
