Позиционирование каретки в TStringGrid

{ 
  The following code allows you to position the caret 
  in a cell (InplaceEditor) of a StringGrid. 
  We need a Cracker class to access the InplaceEditor. 

}

type
  TGridCracker = class(TStringGrid);

   {...}

implementation

{...}

procedure SetCaretPosition(Grid: TStringGrid; col, row, x_pos: Integer);
begin
  Grid.Col := Col;
  Grid.Row := Row;
  with TGridCracker(Grid) do
    InplaceEditor.SelStart := x_pos;
end;

// Get the Caret position from the focussed cell 
// Ermittelt die Caret-Position der aktuellen Zelle 
function GetCaretPosition(Grid: TStringGrid): Integer;
begin
  with TGridCracker(Grid) do
    Result := InplaceEditor.SelStart;
end;

// Example / Beispiel: 

// Set the focus on col 1, row 3 and position the caret at position 5 
// Fokusiert die Zelle(1,3) und setzt den Cursor auf Position 5 

procedure TForm1.Button1Click(Sender: TObject);
begin
  StringGrid1.SetFocus;
  SetCaretPosition(StringGrid1, 1, 3, 5);
end;
