Have you checked to make sure that the OnChange events for the other dropdown lists are referencing the correct methods in your code? They might all be referencing DD1_SelectedIndexChanged.

Incidentally, you really should think about refactoring some of your code as you have a lot of repetition there. The list population code should really be moved into the On_Init event too.
