title: How to hide a content place holder in a .aspx page?
body: <p>My master page has 3 content place holders:</p>
  
  <pre><code>1. left side bar
  
  2. middle content area
  
  3. right side bar
  </code></pre>
  
  <p>So it looks like:</p>
  
  <pre><code>&lt;div id="left"&gt;&lt;/div&gt;
  &lt;div id="content"&gt;&lt;/div&gt;
  &lt;div id="right"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>On a particular view page (.aspx) that inherits the master page, I want to now show #3 (right side bar).</p>
  
  <p><strong>So I don't want the  to be rendered at all.</strong></p>
  
  <p>How can I do this?</p>
