Hi Steve,
The version you mentioned as the one you use can be wired to spell-check a RadGridView control. I suggest you look through
this help article for further details. The documentation describes the latest version of the control, so there may be some features missing in the 2011 Q3, but the basic use of RadSpellChecker for RadGridView is the same.
Feel free to contact us if you have other comments or questions.
Regards,
Petya
