Based on this viedo: VB.net-Auto generate row number to datagridview in windows application-winforms, you can set the DataSource and this code puts the rows numbers, works like a charm.

private void DataGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    // Add row number
    (sender as DataGridView).Rows[e.RowIndex].HeaderCell.Value = (e.RowIndex+1).ToString();
}
