Try this bit of code.

You need to place a popup menu on your form and assign it to your
StringGrids popup menu.

procedure TForm1.StringGrid1MouseDown(Sender: TObject;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var ACol, ARow: LongInt;
begin
  {Check if the mouse button pressed was the right button}
  if Button = mbRight then
  begin
    {Get the Row and Col click on}
    StringGrid1.MouseToCell(X, Y, ACol, ARow);
    {Check that the user clicked on a valid Row and Col}
    if (ACol <> - 1) and (ARow <> - 1) then
    begin
      {Check if the user has not clicked on a fixed col or row
      as you cannot select a fixed col or row}
      if (StringGrid1.FixedCols <= ACol) and (StringGrid1.FixedRows <= ARow) then
      begin
        {Make the current selection equal to the Row and Col clicked on}
        StringGrid1.Col := ACol;
        StringGrid1.Row := ARow;
      end;
    end
  end;
end;
