title: foreach Control ctrl in SomePanel.Controls does not get all controls
body: <p>I have a panel with a bunch of labeles and textboxes inside of it.</p>
  
  <p>The code:</p>
  
  <pre><code>foreach (Control ctrl in this.pnlSolutions.Controls)
  </code></pre>
  
  <p>Seems to only be finding html table inside the panel and 2 liternals.
  But it does not get the textboxes that are in the html table.
  Is there a <strong>simple</strong> way to get <strong>all</strong> the controls inside of a panel <strong>regardless of the nesting</strong>?</p>
  
  <p>thanks!</p>
