Thank you probie:

1. you give out copy and paste sample,
   how about CUT and paste?
2. Your sample only work with single
   records, how about multivalues?
   I mean if i want cut 5 records at
   the same time and then paste them   back again, how to do it?


Thanks

  for lp0 := 0 to BufferItems.Count-1 do begin
   ListView1.Items.Insert(idx).Assign(BufferItems[lp0]);
  end;
 end else begin
  for lp0 := 0 to BufferItems.Count-1 do begin
   ListView1.Items.Add.Assign(BufferItems[lp0]);
  end;
 end;
end;

procedure TForm1.CutButtonClick(Sender: TObject);
// Cut
var lp0 : integer;
begin
 BufferItems.Clear;
 for lp0 := ListView1.Items.Count-1 downto 0 do begin
  if ListView1.Items[lp0].Selected then begin
   BufferItems.Add.Assign(ListView1.Items[lp0]);
   ListView1.Items[lp0].Delete;
  end;
 end;

end.
