 InitializeComponent();
 textBox1.text = g.ToString();

Answer 1

Solution is very well described here

private void DataGridViewMouseDownHandler(object sender, MouseEventArgs e)
{
    if(e.Button == MouseButtons.Right)
    {
        var hti = dataGridView.HitTest(e.X, e.Y);
        dataGridView.ClearSelection();
        dataGridView.Rows[hti.RowIndex].Selected = true;
    }
}

this.dataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.DataGridViewMouseDownHandler);
