Answer :

1) We set AutoPostBack to false for the RadioButtonList control. 2) In the PreRender event for the page, we manually add the new doPostBack function to each List item in the radio button list by looping through the list items in the RadioButtonList. 3) The code is as follows:

for (int i =0; i < rbList.Items.Count; i++)
{
    rbList.Items[i].Attributes.Add("onclick", "javascript:setTimeout('__doPostBack(\\'rbList$"+ i +"\\',\\'\\')', 0)");
}

4) The code in the onclick event function call matches the structure of what ASP.Net 3.5 + C# automatically generate.

After this fix, both radio buttons had onclick events functions and original functionality was restored.
