[c#] How to get values from selected row in DataGrid for Windows Form Application?

Title is pretty self-explanatory. I've got a DataGrid for a Windows Form Application, and I want to be able to store the values of a selected row. What is the easiest way to go about doing this?

I have found this chunk of code as an example in my search, but doesn't work when the DataGrid is sorted differently:

private void grdPatients_CurrentCellChanged(object sender, EventArgs e)
    {
        int row = grdPatients.CurrentRowIndex;

        grdPatients.Select(row);

        ArrayList arrayList = new ArrayList();

        for (int i = 0; i < 3; i++)
        {

            arrayList.Insert(i, (patientsDS.Tables["PatientList"].Rows[row].ItemArray.GetValue(i)));

        }

        textBox1.Text = "" + arrayList[0];

        textBox2.Text = "" + arrayList[1];

        textBox3.Text = "" + arrayList[2];
    }

You could just use

DataGridView1.CurrentRow.Cells["ColumnName"].Value
