title: How to hide a button in Silverlight/WP7?
body: <p>I saw a question here showing to use this:</p>
  
  <pre><code>button.Visibility = Visibility.Hidden;
  </code></pre>
  
  <p>but I only have Collapsed or Visible, and Collapsed removes the button which changes the layout of the controls which I don't want.</p>
  
  <p>Any ideas on how to solve this?</p>
