The complete code for controls in Developing Microsoft ASP.NET Server Controls and Components can be downloaded from MSDN. Too bad I already wrote the DatePicker about an hour ago... this ListView control might be useful though. Lots of interesting goodies here that you might find a place for (HtmlEditor, ScrollablePanel, etc.). Admittedly, it might not take more than a few minutes to create some of these yourself, but I'm sure you have better things to do than write custom controls all day long :-).
