Código Delphi [-]

  DataCol: Integer; Column: TColumn; State: TGridDrawState);
var
        x : integer;
begin
        if (gdSelected in state) then
        (sender as TDBGrid).canvas.Brush.Color := $00C08000
        else
        if (sender as TDBGrid).datasource.dataset.RecNo mod 2 = 0 then
        (sender as TDBGrid).canvas.Brush.Color := clAqua - $000b0b0b
        else
        (sender as TDBGrid).canvas.Brush.Color := clAqua - $00010101;

        (sender as TDBGrid).canvas.FillRect(Rect);

        if Column.Field <> nil then
        begin
        case  Column.Alignment of
         taCenter : x := (Rect.Right - Rect.Left) div 2 - (sender as TDBGrid).canvas.TextWidth(Column.Field.asstring) div 2;
         taLeftJustify : x := 0;
         taRightJustify : x := Rect.Right - (sender as TDBGrid).canvas.TextWidth(Column.Field.asstring);
         end;

        (sender as TDBGrid).DefaultDrawing := true;
        (sender as TDBGrid).canvas.TextOut(Rect.Left + x,Rect.top,Column.Field.asstring);
        end;
end;
