Looks like definitions for methods: Button1_Click() and Button2_Click() are not included in Chapter 2, Listing 2-16: 'Using the UpdateMode and ChildrenAsTriggers Properties'. The AsyncPostBackTrigger entries for each button name the 'Click' event. However, the button entries do not name an 'OnClick' handler.
Thanks in advance for your help!! This is a great book!!!
