I am trying to develop online test tool in ASP.NET, I have used Ajax lookup to get the questions and 4 multiple answers for it. It seems to be working fine. However, the problem is, I can use the back button on the browser navigate to the previously answered question and change or view the answer. I would like to completely disable the back button on the browser as long as they are with in the test application(pages).
Please can someone advise if there is any trick/logic to do this?
Thanks for your help.
