title: Bubbling Events to Parent in ASP.NET
body: <p>I have say this hierarchy in ASP.NET:</p>
  
  <pre><code>page
    user control 1
       user control 2
           control 3
  </code></pre>
  
  <p>What I want to be able to do is that when control 3 (it could be any kind of control, I want to do this generically) has the user do something with it that triggers a postback, it bubbles up some event to user control 2, or maybe even user control 1 (though I could have UC 2 manually bubble the event too).</p>
  
  <p>Again, I want to do this generically, so that the hierarchy can change and it still works.  Maybe there are multiple controls (control 4, etc.) or a data bound control.  Is this possible?</p>
  
  <p>Thanks.</p>
