Bands and Fixed Cells

In my grid I am using bands of four lines to show different "rooms". However, the fixed cells in teh left colium all remain the same colour. I would like to have them affected by the bands also, but I cannot seem to get it to work. My current solution is this

     MainGrid.CellProperties[0,j].BrushColorto := clskyblue;
      MainGrid.CellProperties[0,j].BrushColor := clwhite;

Which is almost what I need, however, the other cells have a mirrored effect which I like but can't seem to emulate.

Any help greatly appreciated.
   

You can use the event
OnGetCellGradient, for example: 


procedure TForm3.AdvStringGrid1GetCellGradient(Sender: TObject; ARow,
  ACol: Integer; var Color, ColorTo, ColorMirror, ColorMirrorTo: TColor;
  var GD: TCellGradientDirection);
begin
  Color         := clwhite;
  ColorTo       := clskyblue;
  ColorMirror   := clskyblue;
  ColorMirrorTo := clwhite;
end;

Cheers, thanks very much that was exactly what I was hoping for.
