html: Unexpected call to method or property access
<p>I am trying to use Rounded Corner buttons in my ASP.NET website using AjaxControlToolkit's RoundedCornerExtender. When I use this on a Buton control, I get an error saying "htmlfile: Unexpected call to method or property access" to which I can Break/continue.</p>

<p>When I run the sites, it gives me an error "Unexpected call to mathod or property access".Here's the screenshot: <a href="http://img29.imageshack.us/img29/7051/roundedcornersp.png" rel="nofollow">http://img29.imageshack.us/img29/7051/roundedcornersp.png</a></p>
