title: How to handle master page button event in content page?
body: <p>There's more than question and article about the same exact question but I have a couple more related questions and was hoping to get some answers.</p>
  
  <ol>
  <li><p>I've heard of two approaches to find the button and add the handler or use an interface (Check both approaches from <a href="http://forums.asp.net/p/1048699/1476660.aspx">here</a>) .. Which one do you suggest ?</p></li>
  <li><p>If you could please illustrate the 'Interface' option with some code and where to class the interface file cause it's not readable in the page when I try to inherit it!</p></li>
  </ol>
