UpdatePanel initial call
<p>I am using an UpdatePaenl in an asp.net page. 
It has a button to trigger it. I'm able to show "Loading" when the button is pressed. 
Here's my issue: I need it to show "Loading" when the page is first called, not just when a button is pressed.</p>

<p>I would imagine that JavaScript would be used to trigger the UpdatePanel when the page is first loaded.</p>

<p>Any ideas are greatly appreciated. Thanks</p>
