Controls, controls...

I've been thinking today - there ought to be a Wiki that lists controls, either for WinForms, ASP.NET and/or GTK#.
It's pretty annoying to have to create a new control just because you can't find one and then, a couple of months later, finding it...
Does anyone know about something like this?
