ASP.Net Ajax Update Panel Quirks

Mainly as a reference for myself, when working with the ASP.Net UpdatePanel remember the following limitations, I have encountered sofar:

• Radiobutton-triggers only work if you set no default value (you can set it from the codebhind) see: http://forums.asp.net/t/1126914.aspx
• Script-blocks don't work if you want it anyway there is a nice solution here: http://weblogs.asp.net/infinitiesloop/archive/2007/09/17/inline-script-inside-an-asp-net-ajax-updatepanel.aspx

For now, I am a big fan of the updatepanel because it gives me the user experience benefits of Ajax without the (architectural) impact.
