Where I currently work we use a lot of hand made custom web controls for things like dropdown lists, auto-complete boxes, etc. and while I have added things to these controls I never really felt like I completely understood what the heck I was doing.
So, my question, are there any good books out there that might help me understand / build some custom webcontrols?
My environment: .net, c# 3.0, linq, etc
Here are some good links:

Developing server controls is a really good way to learn more about the ASP.NET life cycle as well.
