ASP.NET AJAX Page Methods from UserControl

The response TheXenocide gave would seem to work, but the developers state, "Control Methods for ASP.NET AJAX is provided "as is" with no guarantees or warranties express or implied, including implied warranties of fitness for a particular purpose, merchantability, and non-infringement."

If you are looking for a long term solution I would consider going with webservice methods. Either that or don't use a usercontrol. You can nest an aspx page within another with an Iframe.
