  <p>If not, how can I change the color of the whole <code>DataGridViewRow</code>? I tried this code, but it does not change the color:</p>
  
  <pre><code>DataGridViewRow row = new DataGridViewRow();
  row.DefaultCellStyle.BackColor = Color.Green;
  row.DefaultCellStyle.ForeColor = Color.Green;
  </code></pre>
  
  <p>As information, my columns are <code>DataGridViewComboBoxColumn</code></p>
