type
   THackAccess = class(TCustomGrid);

 { 
  THackAccess Is needed because TCustomGrid.MoveColumn is 
  protected and you can't access it directly. 

  THackAccess Braucht man, da TCustomGrid.MoveColumn in der 
  Protected-Sektion steht und nicht direkt darauf zugegriffen werden kann. 
}

 // In the implementation-Section: 

procedure MoveDBGridColumns(DBGrid: TDBGrid; FromColumn, ToColumn: Integer);
 begin
   THackAccess(DBGrid).MoveColumn(FromColumn, ToColumn);
 end;


 {Example/ Beispiel}

 procedure TForm1.Button1Click(Sender: TObject);
 begin
   MoveDBGridColumns(DBGrid1, 1, 2)
 end;
