Practical use of sender & EventArgs in Page_Load
<p>I am on the verge migrating all my asp.net WebForms skills to asp.net mvc. So far, I never felt a need to use <code>EventArgs</code> and <code>sender</code> argument, passed to <code>Page_Load</code>. </p>

<p>Can you please point me a couple of scenario, when you leverage theses parameters?</p>
