Web Controls

I would like to share a list of real useful third party webcontrols.

Why? Because there are so many controls on the market actually and it's hard to find the best one.

What I would like to see is not an exhaustive list of controls but more what developers use, and sort this list by true ratings based on your experience.

So if it's working well, I will organise a list like Fabrice did for the tools.

I would like to start by two types of controls I use a lot.

- Menu Control
  - ASP.Net menus Coalesys
I like this one, the only issue I have is that it's quite hard to setup.

- Text Editor 
Rich Text box RichTextbox
Probably the most complete and easy to use
