title: Conflicting RaiseCallbackEvents of ICallbackEventHandler when using a User Control on an ASP.Net Page
body: <p>Hi and thanks for reading.</p>
  
  <p>I am using the ICallbackEventHandler interface to do some client-side processing in an ASP.Net page (VS 2005).  Everything works as expected except under the following situation.  I created a User Control (.ascx) that also uses ICallbackEventHandler and placed it on the aforementioned ASP.Net page.  <strong>Now, the RaiseCallbackEvent fires on the User Control but not on the ASP.Net page.  In other words, it doesn't fire in both places.</strong>  Has anyone else encountered this and have a solution?</p>
  
  <p>To reproduce, just create an ASP.Net page that uses ICallbackEventHandler, a User Control that uses ICallbackEventHandler and place it on the ASP.Net page and you'll see that the RaiseCallbackEvent fires in the User Control but not in the ASP.Net page.</p>
  
  <p>Thanks!</p>
