Also,
Whoever did the Themes support really doesn't know how to use it. You create a page for the controls and use CSS for the rest and use the page declarative (or web.config) to define which theme you are wanting to use.
There are really some fundamental best practices that are completely missing from the .NET project. You should use a basepage for inheritance and build from there. This is (and is not) happening. If you use your basepage as the security module, you won't have to get your connection string but once a page (thus limiting the security exposure) and setup your connection. This is also a good place to start your business logic (as opposed to the data or presentation).
I hope I don't seem to be 'hating' on the project too much. Just trying to offer some constructive criticism and food for thought. I'm actually impressed with the provider work that was done, however some of your override methods are not being triggered due to referencing errors.
Hit me up if you have questions or need examples...
