Hi I am a fresher in asp.net.
In the below situation i want to display question when the button is clicked. I used for loop. But the problem is i can able to display only the last question and option. But if i use response.write all the 3 question and option are displayed. I have placed my code and output below.
Can any one please help me on this.

In program.cs

protected void Button1_Click1(object sender, EventArgs e)
   {
       DatabaseDLL.Quiz ObjQuiz = DatabaseDLL.Manager.DisplayQuestions("General Knowledge");
       if (IsPostBack)
       {
           foreach (DatabaseDLL.Question Q in ObjQuiz.GetQuestions())
           {
               Response.Write(Q.Question1);
               Response.Write(Q.Option1);
               Response.Write(Q.Option2);

               Label1.Text = Q.Question1;
               Label2.Text = Q.Option1;
               Label3.Text = Q.Option2;

           }
       }

   }

In the dll manager class:

public static Quiz DisplayQuestions(string category)
      {
          Quiz ObjQuiz = new Quiz();
          try
          {
              Conn = new SqlConnection("Data Source=HDCHARTOMR1213\\SQLEXPRESS;Initial Catalog=UserDetails;Integrated Security=SSPI");
              Conn.Open();
              SqlCommand Cmd = new SqlCommand("QuizQuestions", Conn);
              Cmd.CommandType = CommandType.StoredProcedure;
              Cmd.Parameters.AddWithValue("@Category", category);
              SqlDataReader reader = Cmd.ExecuteReader();
              while (reader.Read())
              {

                  Question ObjQuestion = new Question(reader[0].ToString(), reader[1].ToString(), reader[2].ToString(), reader[3].ToString());
                  ObjQuiz.AddQuestion(ObjQuestion);
              }

              reader.Close();

          }
          catch (Exception e)
          {
              Console.WriteLine(e);
          }
          finally
          {
              if (Conn != null)
              {
                  Conn.Close();
              }
          }
          return ObjQuiz;

      }

public class Question
   {
        public string Option1 { get; private set; }
        public string Option2 { get; private set; }
        public string Question1 { get; private set; }
        public string Category { get; private set; }
        public Question(string Question1, string Option1, string Option2, string Category)
        {
            this.Question1 = Question1;
            this.Option1 = Option1;
            this.Option2 = Option2;
            this.Category = Category;
        }

   }

public class Quiz
    {
       public List<question> ObjQuestion = new List<question>();
       public void AddQuestion(Question NewQuestion)
       {
           ObjQuestion.Add(NewQuestion);
       }
       public List<question> GetQuestions()
       {
           return ObjQuestion;
       } 
        public Quiz()
        {
           
        }
    }
