Spell checker

Hi,

I was wondering if you have any recommendation on how to implement a custom spell checker on asp.net. I basically want to provide my own dictionary and do the usual spell check.

Thanks

Telerik has an Ajax Spell Checker Component here.It's not free though. Don't know if there's an equivalent library in JS or jQuery which is freeware that has the same functionality.

Thanks for the link but I'm looking for an open source one if possible.
