Removing the vertical scrollbar from a TDBGrid
 

In order to remove the vertical scrollbar from a TDBGrid component,  you
must override its Paint method.  Inside the Paint method you must call the
SetScrollRange API procedure to set the min and max scroll values to zero
(this disables the scrollbar), and then call the inherited Paint.  The code
below is a unit containing a new component called TNoVertScrollDBGrid that
does this.  You can copy the code into a file called NEWGRID.PAS, and add it
to the component library as a custom component.
 

unit Newgrid;

interface

uses
  WinTypes, WinProcs, Classes, DBGrids;

type
  TNoVertScrollDBGrid = class(TDBGrid)
  protected
    procedure Paint; override;
  end;

procedure Register;

implementation

procedure TNoVertScrollDBGrid.Paint;
begin
  SetScrollRange(Self.Handle, SB_VERT, 0, 0, False);
  inherited Paint;
end;

procedure Register;
begin
  RegisterComponents('Data Controls', [TNoVertScrollDBGrid]);
end;
end.
