title: asp:RadioButton and javascript function $find()
body: <pre><code>&lt;asp:RadioButton ID="myButton" Text="Option" GroupName="group" runat="server" /&gt;
  </code></pre>
  
  <p>Why in this case javascript function call <code>$find('&lt;%= myButton.ClientID %&gt;')</code> return <code>null</code>? I need to detect/change value in client javascript. <code>$find()</code> should be shortcut for <code>Sys.Application.findComponent()</code>.</p>
  
  <p>UPDATE: There is no problem with ID, i tried $find() in chrome console with real rendered id and still getting null. And i want to get Ajax control, not DOM element.</p>
