Best free richtextbox for ASP.NET 2.0?

What is the best rich text box to use with ASP.NET 2.0?

I need to allow users (non technical) format their own email with simply styling, but it needs to be shown as they type, rather than a markup language with a preview.

From stackoverflow

• I've just started using WYMeditor, and it seems pretty good so far.

• Try this:

  http://freetextbox.com/

  My only complaint is that is doesn't work (but degrades gracefully) in Chrome. I expect a fix for that sometime soon, anyway.

• http://www.codeplex.com/rte

• no problems with http://tinymce.moxiecode.com/ and has some nice features too. it's written in javascript as is http://www.fckeditor.net/

  http://tinymce.moxiecode.com works in chrome

  Jason : Unfortunately, this won't work with Update Panels. ;( http://weblogs.asp.net/cjdevos/archive/2008/03/03/ajax-extender-for-tinymce-including-fix-for-updatepanels.aspx and http://forums.asp.net/p/1034078/1584748.aspx

  Jason : Correction - Moxiecode is the one that has trouble with Update Panels. We are working with FCKEditor now... which seems great so far. Thank you.

  DrG : yeah fckeditor is awesome, i've used it in several projects

• I would throw my vote in for

  http://www.fckeditor.net/

  Despite it's 'almost naughty' name it's a great rich text box and very easy to use.

  Wyatt Barnett : Ah, that name. There was one (almost career-ending) incident when I suggested we use it for a project and someone read through the name.
