Answer 1

Set AutoPostBack="true" for your RadioButtonList

<asp:RadioButtonList AutoPostBack="True" ID="selectedYesNoQuestionBlock7" 
      runat="server" RepeatDirection="Horizontal" 
                OnSelectedIndexChanged="Question7GotAnswered">
 ...
</asp:RadioButtonList>

Answer 2

Look at the event exposed by the RadioButtonList control and put your code in the proper event handler. I guess you should set to True AutoPostBack of the control as well.
