 If I understand your question correctly, I think this is what you 
are looking for:

procedure TOptionsForm.PageControl1Change(Sender: TObject);
//To save resources with a TPageControl you can use the following 
TPageControl OnChange event handler:
//Put this in at top after interface: type TMyWinControl = 
class(TWinControl);
var
  i: Integer;
begin
  with Sender as TPageControl do
    for i := 0 to PageCount - 1 do
      if Pages[i] <> ActivePage then
        TMyWinControl(Pages[i]).DestroyHandle;
end; //PageControl1Change
