title: ASP.NET implement anchor without postback
body: <p>I'm working on an ASP.NET web app in VS2010,C#, I want to make something like this page:</p>
  
  <pre><code>http://www.just-eat.co.uk/restaurants-simplyscrumptious/menu
  </code></pre>
  
  <p>when you click on food categories on left, page jumps to that category without any postback, how can I achieve it?</p>
