title: Get value from a cell in DataGridView into a TextBox when using BindingNavigator
body: <p>I want to populate some text boxes while clicking the next row on the <code>BindingNavigator</code>.</p>
  
  <p>I can use for the first text box:</p>
  
  <pre><code>textBox1.Text = dataGridView1.CurrentCell.Value.ToString();
  </code></pre>
  
  <p>but I also want to get the info from cells 2 and 3 into <code>textBox2</code> and <code>textBox3</code>. How can I access these based on what row is currently selected?</p>
