That's a statement, not a question.

You are going through the entire DataGridView so you are probably just picking up the last "Row" which is where the user can add a row.

Try stepping through your code to confirm this, or set val to a strange number at the start of the loop to prove the point e.g.

C#

private void metroGrid1_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
        {
            int val = -99;
            foreach (DataGridViewRow row in metroGrid1.Rows)
            {
                val = Convert.ToInt32(row.Cells["quantity"].Value);
            }
            totPenTxt.Text = val.ToString();
}
