title: Finding what method is called
body: <p>I have an ASPX page with no code behind (that is, no <code>.aspx.cs</code> with the same name).  In the code is this line:</p>
  
  <pre><code>&lt;div style="overflow: hidden; text-align: center; z-index: 105;"&gt;
      &lt;%= MainNavBarHTML %&gt;&lt;%= SubNavBarHTML %&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I've searched the rest of the program for <code>MainNavBarHTML</code> and <code>SubNavBarHTMl</code>, but can't find any reference to them.  How do I find what fills those elements?</p>
