Event handler for group radio button
Hello
I am developing a multiple choice quiz application
Each question has four options to choose from by the user.
My questions are
-how can i set eventhandler for the radio buttons to make the user know if the option choosen is right or wrong
-I dont want the user to know the right or wrong answer untill they finish the quiz
-I want the event handler to also show the numbers of right and wrong answers with total score of the user at the end of the quiz
Regards
