I am trying to rebind a "cb_SAACode" when "cb_bondClass" selected index is changed. "cb_SAACode" seems to be rebinding but it is not refreshing on the page. I tried to use the "FindControl" method to find "cb_SAACode" but it doesn't seem to help at all. Attached are the code snippets. Note, this is not the full code so it will not compile. Thanks for the help.
