asp.net quiz

rambo85

Hi, I'm new to asp.net, I'm creating a quiz, I have a set of questions that are stored in an array and they are stored in session state, when I load the first page of the quiz a question is randomly chosen with a set of answers. when I move forward a page and then back
I want the same question to be displayed but it keeps displaying a new question, I tried storing the outputted question in session and then loading it before, but it doesn't work any suggestions???

Thanks in advance

namespace Quiz
{
    public partial class page2 : System.Web.UI.Page
    {
        string question;
        string[] questions;
        string[] answers;
       
        public Random rnd = new Random();

        protected void Page_Init(object sender, EventArgs e)
        {
            

                questions = (string[])Session["Questions"];
                int randNum = rnd.Next(questions.Length);
                question = questions[randNum];
               
          
        }//End init
       

        protected void Page_Load(object sender, EventArgs e)
        {


            if (Session["selectedValue1"] != null)
            {

                question = Session["questionAsked"].ToString();
                lblQ1.Text = question;
                rbAns1.SelectedIndex = (int)Session["selectedValue1"];
            }


            lblQ1.Text = question;
          
            

            answers = (string[])Session["Answers1"];
            for (int i = 0; i < answers.Length; i++)
            {

                rbAns1.Items[i].Text = answers[i];

            }
               


            
          
            
        }
     
        protected void rbAns1_SelectedIndexChanged(object sender, EventArgs e)
        {
            Session["selectedValue1"] = rbAns1.SelectedIndex;
           
           
        }

        protected void btnPrevious_Click(object sender, EventArgs e)
        {

            Session["questionAsked"] = question;
            Response.Redirect("StartPage.aspx");
        }

        protected void btnNext_Click(object sender, EventArgs e)
        {

            Session["questionAsked"] = question;
            Response.Redirect("page3.aspx");
          
        }

Why not have one page to handle the quiz? Wouldn't that make it a little easier?

rambo85

only allowed one question per page im afraid!

This is the first page

Use query strings!

private string [] questions = { "Q1","Q2","Q3","Q4","Q5","Q6","Q7","Q8","Q9","Q10" };
        private string [] answers = { "A1", "A2", "A3", "A4", "A5", "A6", "A7", "A8", "A9", "A10" };
        private int[] order = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            if (null == Session["Questions"])
            {
                order = order.OrderBy(o => Guid.NewGuid()).ToArray();
                //Stuff the order into the session.
                Session.Add("Questions", order);
                Response.Redirect("~/Default.aspx?page=1");
            }
            else 
            {
                order = (int[])Session["Questions"];               
            }
            

        }
        protected void Page_Load(object sender, EventArgs e)
        {
            int page = 0;           
            if (Request.QueryString["page"] != null)
            {
                int.TryParse(Request.QueryString["page"], out page);
            }
            if (page != 0)
            {
                Label1.Text = questions[order[page]];
            }
            
        }

You just need to add paging which is trivial (next link = current page + 1). Also, error checking.

It will load like a full page each time if you do it right.

I see you use multiple answers per question, you can use the same method, as you don't have to shuffle the multiple choice (only the display of it, you can assign static values to the radio button or whatever you use it and compare against an array of answer keys). The order list always maintains to order the questions will be asked, how they relate to the answers and the answer key itself! In one simple variable!
