Answer 1

if you are looking to get the Value of Selected Cell then All you Need to is trigger the DataGridView KeyDown Event and write the code as

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            txtName.Text = dataGridView1.CurrentCell.Value.ToString();
            //do whatever you want to
        }
    }

and if you want to get the whole row and perform operations, you can do it as

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            int row = dataGridView1.CurrentCell.RowIndex;
            txtID.Text = dataGridView1.Rows[row].Cells[0].Value.ToString();
            txtName.Text = dataGridView1.Rows[row].Cells[1].Value.ToString();
            //do whatever you want to
        }
    }
