What is the purpose of the arguments Object o and EventArgs ea, in ddlChooseReport_Function (ASP.net)?
<p>I'm curious as to the purpose of this method signature in ASP:</p>

<pre><code>protected void ddlChooseReport_Function(Object sender, EventArgs e) 
</code></pre>

<p>because in the method body afterward, it never mentions either parameter</p>
