Question

Does anyone know of a C# spell check library that would underline misspelled works in a windows form text box? In the past, I’ve used NetSpell and works great if users use the dialog box.

I’m thinking I might be able to automatically call the spell check while text is being updated and underline the text. Anyone have any good ideas on what would be the best way to go about doing it?

We are using Infragistics‘ components.
They offer WinSpellChecker which seems doing the job you are looking for

There is also NHunspell – free open source spell checker what might be used to easily develop control you are talking about
