In case you have not heard yet (as I tend to find out about things a bit late thanks to the amount of email I get), the Atlas Control Toolkit has been released and is up for download on the ASP.NET website. You can download the toolkit at http://atlas.asp.net/default.aspx?tabid=47&subtabid;=477. The toolkit includes some cool controls such as a Collabsable Panel, HoverMenu, PopupControl, and more. Full demos of each control are also available on the site.
