Beginner: Multiple Choice Quiz

Question

I'm a Beginner. I'm making a Multiple Choice Quiz. I want the results from ALL my Buttons to display in my Label when the user Submits their answers. How do I do this?

(2 Questions) 4 Radio Buttons
1 DropDown (ID="DropDownList1")
1 CheckBox (ID="CheckBoxList1")
1 FeedBack/ShortAnswer TextBox
Submit Button
Results Label

Basically I want it to display like this:

Results:

You answered 2 questions correctly

Question 1 is Correct

Question 2 is Incorrect. The correct answer is True.

Question 3 is Correct

I like apples because they are good for your health.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Text;
using System.Web.UI.WebControls;

namespace Project4
{
    public partial class Project4 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }


        protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }


        protected void ClickHereForMore_Click(object sender, ImageClickEventArgs e)
        {
            Response.Redirect("https://my.sunysuffolk.edu/web/home-community/activities-information");
        }


        protected void SubmitButton_Click(object sender, ImageClickEventArgs e)
        {

            if (RadioButtonTrue.Checked)
            {
                lblResults.Text = "Question 1 is Correct";
            }
            else if (RadioButtonFalse.Checked)
            {
                lblResults.Text = "Question 1 is False. Correct answer is True.";
            }
            if (RadioButtonYes.Checked)
            {
                lblResults.Text = "Question 2 is Correct";
            }
            else if (RadioButtonNo.Checked)
            {
                lblResults.Text = "Question 2 is False. Correct answer is True.";
            }





        }

        protected void FeedBack_TextChanged(object sender, EventArgs e)
        {
            lblResults.Text = FeedBack.Text;

        }


    }
}

One of my problems right now is that the RadioButton is displaying only the Results of Question 2. I think I know why, but I don't know how to fix it so that it will display both Question 1 and 2 answers. I can only imagine this issue becoming bigger when I try to do the same for the other buttons. Also the feedback text isn't displaying.

Hint: `+=` adds to the text already there. – Heretic Monkey Mar 04 '19 at 22:20 — Heretic Monkey, Mar 04 '19 at 22:20

For lblResults.Text = "Question 2 is Correct"; you need to append the text. As it stands you are replacing it.

Use the following instead, note += to append the string:

if (RadioButtonYes.Checked)
{
   lblResults.Text += "<br>Question 2 is Correct";
}
else if (RadioButtonNo.Checked)
{
   lblResults.Text += "<br>Question 2 is False. Correct answer is True.";
}

Don't forget about the newline character `\n` – Jesse de Wit Mar 04 '19 at 22:26
For the new line i needed to use "
" – KPIT Mar 04 '19 at 22:57
`
` is the preferred choice for HTML5 see https://stackoverflow.com/a/1946446/4665 . However `
` is acceptable. – Jon P Mar 04 '19 at 23:41
Thanks for that, and the link was helpful. – KPIT Mar 05 '19 at 00:34
