title: How do I make a TreeNode not visible? (C#)
body: <p>There is probably a really straightforward answer to this but I'm having difficulty finding it.</p>
  
  <p>Simple, I have a TreeNode and I would like to make its visibility false. (or another way of not allowing it to be shown until required).</p>
  
  <p><b>Edit - Another Question?</b></p>
  
  <p>I'm confused as to how there isn't a Visible attribute but then there is the property:</p>
  
  <pre><code>Node.PrevVisibleNode;
  </code></pre>
  
  <p>What is the difference between this and <code>Node.PrevNode</code>?</p>
  
  <p>Thanks,</p>
