Is there a rich text editor control that does both spell AND grammar checking?

Question

I'm looking for a winforms or wpf control that can do both spelling and grammar checking in english and also do red & green squiggly underlines, similar to MS Word.

So far, all I've been able to find are spell-checker controls. I'd be open to good spell checking and grammar checking libraries as well - if you can recommend an integration point with the editor that allows for the underlining.

But its little lengthy !

Not easy like plug it in and work.

But it may work :)
