title: ASP.NET web forms: UpdatePanel no-js fallback for AutoPostback?
body: <p>I have an <code>UpdatePanel</code> which I've decided to try out, and I assumed that all of its behaviors would be taken care of by the asp.net mechanism when javascript is turned off. One of the behaviors is doing some UI changes when a dropdownlist or checkbox are changed. Those changes are revealing sections of the form or changing the Text of some <code>&lt;asp:Label&gt;</code> controls. When JS is enabled, my <code>AutoPostback="true"</code> attribute on the checkbox makes its change event update the form like it needs to be. However when the JS is not enabled, it does nothing - and I'd like it to resume the kind of behavior it had before I started using the <code>UpdatePanel</code> - which is to refresh the page each time with updated server data. Are there any tweaks one can make to the <code>UpdatePanel</code> properties to achieve this kind of fallback solution?</p>
  
  <p><em>(no, this isn't a real requirement for the job at hand, but I expected the asp.net's server controls would auto-solve this kind of issue in the first place, so I'd like to know if there's some way.)</em></p>
