Unfortunately, even when AutoPostback is enabled on a drop-downlist it
won't trigger a postback unless the selected value is *different* from
the previous one (or unless the SelectedIndex property actually
changes). Merely clicking on it will not do the trick.

This exposes a fundamental problem with Satish's design. Since the DDL
is preloaded with data it will not necessarily work in the intended
fashion. The best approach is to preload the other controls with
relevent data (based on the initial selection) during the FormView
DataBound event.
