title: What's the different between ASP.NET AJAX pageLoad() and JavaScript window.onload?
body: <p>I'm working with ASP.NET AJAX and want to understand the difference between these two snippets:</p>
  
  <pre><code>function pageLoad(sender, eventArgs) { }
  </code></pre>
  
  <p>and </p>
  
  <pre><code>window.onload = function() { }
  </code></pre>
  
  <ul>
  <li>Do they act the same? </li>
  <li>Or is one called before the other? </li>
  <li>Or will one be called automatically and the another not?</li>
  </ul>
