Hi,
I have the same issue with radio buttons. I tried <asp:UpdatePanel
ID="updAuthoptions" runat="server"
> ChildrenAsTriggers="false" UpdateMode="Conditional">.
My requirement is that another set radiobuttons(in a panel) need to get
enabled when an option is chosen from the first radio button list .
The page doesn't jump, but then the 2nd set of radiobuttons does not get
enabled, although the control goes to its selected index changed event.
Could you tell me if I am missing anything?

It may be easier for me to help you if you post your current code. Until
then, it sounds like you need to use the Triggers control of the UpdatePanel
to use the first RadioButtonList as a Trigger. If you post your code I can
show you how you should do this for your situation. Good Luck!
