In asp.net, how can I tell what triggered an additional page_load call?
<p>Greetings.</p>

<p>Is there a good way to determine what is calling my Page_Load method?  I've got a few Componentart WebUI grids that call it, although I've checked all of those (using the gridName.IsCallback property).  I've also got an update panel, but I'm not sure how to check if it is the caller.</p>

<p>I'm betting there is a property somewhere that will tell me.</p>

<p>Thanks!</p>
