Vista - Scrolling grid, locking header row

Hi,

What would be the best approach to take with this problem? I have a grid
that needs to be able to scroll both horizontally and vertically, as it
could conceivably be bigger in than the viewport in either direction.
Please see:

The problem is, the header row needs to be fixed. That is, when the grid is
scrolled horizontally, the header moves with the rest of the grid so that
the columns still line up, but when it is scrolled vertically the header
stays put so that it is always visible.

The only thing I can come up was using two grids in a horizontal-only
scrollviewer with SharedSizeGroup for the columns and then putting the
content rows in a vertical-only scrollviewer, problem is that having them
both in the horizontal scrollviewer means having to scroll the the right of
the grid in order to get to the vertical toolbars.

Is there a way to take a ScrollViewer with no visible scrollbars, and link
it to a <scrollbar> elsewhere that then acts exactly like the vertical
scrollbar of the scrollviewer should?

private void ScrollChanged(object sender, RoutedEventArgs e){
HeaderRow.ScrollToHorizontalOffset(DataRows.HorizontalOffset);
}
