Recently at my job, I've been asked to adding a ReCAPTCHA field to our self-service password reset page that's provided by Microsoft's Forefront Identity Manager. But I'm not too knowledgeable about ASP. I've added the ReCAPTCHA control and it is communicating with Google to refresh the page. But I'm not sure how to actually validate the ReCAPTCHA answer. Would I have to put the ReCAPTCHA validation code in the event handler for the submit button? Or would I have to add it to the whole page itself?
