I am writing an online exam application.After login successfully, the student reaches to the question1.aspx , after answer the question by click the radiobutton, he reaches the question2.aspx....Assume that there are 5 questions, after he answer the question in question5.aspx he reaches the result.aspx.This page will show the student's score.

My problem is : how to get the value of the student's answer in each question( to compare it with the right answer in the database) of all the questionx.aspx and show the result in the result.aspx page.

Well you can always temporarily store the scores for each correct answer in the following manner:

Lets assume 10 is the score for each correct answer

Session["score"]=10;
Session["score"] = (int)Session["score"] + 10;

Finally you can assign the final score to a label control in the following manner:

lblScore.Text=Session["score"].toString();

hope this would be of help.Please don't forget to click thanks button if the suggestion is of real help .
