Hi C# newbie,
I give you beneath that some answers, but I think it is better to continue
in the newsgroups:
microsoft.public.dotnet.framework.aspnet
and
microsoft.public.dotnet.languages.csharp.
The answers on you page can you use the aspx control dropdownlist instead of
the html dropdown, than you can control that in your aspx.cs using C# code.
To start your javascript you can have a look at the page class. Dificult to
find on msdn because a lot of things are named page. So search for page
registerstartup.

I hope this helps,
Cor
