How to select whole row when user clicks one cell or consective/concurrent cells in a DataGridView

Hello.

I'm developing a C# application with a DataGridView using Visual Studio Community 2015,  .NET Framework 4.6.00081 on a Dell laptop.

When a user clicks a cell in a DataGridView, I would like my program to select the whole row of where the cell was clicked.  I tried this:

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            dataGridView1.Rows[e.RowIndex].Selected = true;
        }

and it works fine if the user only selects one cell.  It does not work if the user selects consecutive/concurrent cells in different rows.

Does anybody know how I can select the complete row/rows of whatever cells a user clicks?

Any help would be gratefully appreciated.

Thanks,
Tony
