Its not possible as its browser functionality. You can not handle that. Opening exam in window without toolbar can help you,but that also can't be the ultimate solution.

Maintaining the user state should be implemented in business logic. Even though user refreshes, your code should be capable enough to handle it.

And that also not possible every time. The only thing you can do is to warn the user of side effects.

Store the information in the database so it remains persisted.

Store the data in an xml file or database, whatever you are comfortable with. You can re populate the fields on refresh.
Also display a warning saying that what will happen if the user refreshes the page.
Maybe it can be done using javascript but I don't think you should try to overrride the client's browser funtionalities.

If you are comfortable with JQuery then at background you can send client data to server to maintain state of client in database/session. If client refreshes browser you can resume him from that last state saved in database/session. For webmethod demo you can refer following links
