How to save values when i click previous button in asp.net
<p>I have created online exam application (web based) in asp.net c#. In my application first form includes dropdownlist for tests &amp; start button. When i select particular test from dropdownlist &amp; after clicking to start button it goes to the next page. It includes one label for question, radiobuttonlist for answers, next &amp; previous button.In first form in the click event of start button i have created non repeated random values ( for question ids) i.e stored in array.when it redirects to another page then 1st question from that array will display with answers &amp; after clicking next button next question will appear, here i have inserted selected values(answers selected in radiobuttonlist) by user in database to calculate score. Problem is with previous button, when i click to previous button then it goes to previous button but i want earlier selected values by user to be bind with that radiobuttonlist. how i can do this? </p>
