Determining ASP.NET client ids
<p>This question is similar to <a href="http://stackoverflow.com/questions/546392/forcing-client-ids-in-asp-net">http://stackoverflow.com/questions/546392/forcing-client-ids-in-asp-net</a> but not quite.</p>

<p>ASP.NET generates clientids according to its own internal mechanism. I would like to run a xmlhttprequest query in the background to do an update and selectively reload some of the controls. My plan is to run the query and regenerate the page in the background, but only selectively rendering the controls I want to update - then just replace the html of those controls with the new ones.</p>

<p>My question is, can I expect the clientids to be the same (since I'm generating the same page) and is there any thing else I need to be aware of if I want to update asp.net-generated html through javascript?</p>
