I am working on an WebForms app, and we want to put a speed bump, for lack of a better term, in for the users at a particular point in the app. There is a particular action which is not supposed to be undone. So when they click the button to do that action we want to display a small confirmation window, have them enter a random string that we give them. Once they enter that string, and it matches the corresponding label, the submit button becomes enablesand they can perform the action. But for the life of me I can't figure out a good way to do this client side with WebForms. Is there a simple mechanism to use this type of workflow without a ton of post back events?
Note: This is an internal app where high security isn't truly a necessary requirement in this case. As I said, this is meant to be something to slow the user down slightly.
