body: <p>What are the available ways to pass a parameter to a <code>UserControl</code> ?</p>
  
  <p>I know the session option but actually I don't prefer it because it'll retain when any exception is occurred. I mean I prefer something like the QueryString (rely on the call or request).</p>
  
  <p>Note: My <code>UserControl</code> will be shown throught a modal popup using JQuery.</p>
