Willem Odendaal is looking for feedback on the best book for learning to create server controls. Personally, I've used books one (Developing Microsoft ASP.NET Server Controls and Components) and three (Professional ASP.NET Server Controls). Three is in my car so I can get to it whenever I need it. It is probably the most used book in my library. I read through it in a weekend, and reference it all the time. Of course, I've always been fond of the Wrox books!
