Auto Spelling checker and corrector for textbox control in ASP.Net

Question

Hi,

I want to know how can we provide spell checkers in textbox in any online website. I mean when user writes something then automatically spelling should be checked in background and red/blue underline should come if there is any sort of problem.

Auto spell correction is also included in same. Means if text that much able to be corrected automatically, then it will be corrected automatically like MS Word is using. I need some help in this scenario.

Thnxx
