title: do i need to unregister events in asp.net
body: <p>I have a web user control that contains several other (web user) controls and subscribes to events the children raise.</p>
  
  <p>I saw someone somewhere  in a similar situation providing Dispose() on the containing control and unregistering the events it had subscribed to. </p>
  
  <p>Isn't it all going to be blown away when the request processing completes? / Is unregistering those events necessary? </p>
