How to display Check Box Text

[QuestionPlease]

My Question is how do I get the check boxes text to display the addons for meals below
Add-ons
• For a hamburger, the three add-on items are: (1) Lettuce, tomato, and onions; (2) Mayonnaise and mustard; and (3) French fries. The price of each is 75 cents.
• For a pizza, the three add-on items are: (1) Pepperoni, (2) Sausage, and (3) Olives. The price of each is 50 cents.
• For a salad, the three items are (1) Croutons, (2) Bacon bits, and (3) Bread sticks. The price of each is 25 cents

my code isn't showing anything on the form

private void hamburger_CheckChanged(object sender, System.EventArgs e)
        {
            if (radioHamburger.Checked == true)
                ResetChecked();

            groupBox2.Text = " Add-on Items ($ .75/each)";
            checkBox1.Text = "Lettuce, tomato, and onions";
            checkBox2.Text = "Mayonnaise and mustard";
            checkBox3.Text = "French fries";
        }

        private void pizza_CheckChanged(object sender, System.EventArgs e)
        {
            if (radioPizza.Checked == true)
                ResetChecked();
            groupBox2.Text = "Add-on Items ($ .50/each)";
            checkBox1.Text = "Pepperoni";
            checkBox2.Text = "Sausage";
            checkBox3.Text = "Olives";

        }

        private void salad_CheckChanged(object sender, System.EventArgs e)
        {
            if (radioSalad.Checked == true)
                ResetChecked();
            groupBox2.Text = "Add-on Items ($ .25/each)";
            checkBox1.Text = "Croutons";
            checkBox2.Text = "Bacon bits";
            checkBox3.Text = "Bread sticks";


        }

this is how the check box's should display the addons(text) so if the user clicks another radio botton the check box text changes to the addons for that meal.

and this is what mine is displaying no text?

Are you sure that those methods are actually handling the appropriate events? Did you paste that code into the code window or did you create the event handlers from the design window?

[QuestionPlease]

No I didn't paste the code in the code window, I don't know why it isn't working???
Do I Have to set something inthe the Form design property settings??

[jmcilhinney]

Do you know for a fact that the code is being run? Place a breakpoint (F9) on each event handler and then try selecting the RadioButtons and see if it is hit.

[QuestionPlease]

just tried it, no their not running what should I do??

[jmcilhinney]

In that case they are not handling the events, which means that either you didn't generate them from the designer or else (and this is quite likely in this case) at some point you cut and pasted the controls from one container to another. Cutting is equivalent to deleting, so the link would be lost at the point. To reattach an event handler, select a control in the designer, open the Properties window, click the Events button, select the appropriate event and then select the appropriate method from the drop-down list.

I decided to put the check box text change in the form load but when I select another radio box it doesn't change and if I add and else instead of if in the second if it wont let me???

private void Form1_Load(object sender, EventArgs e)
        {
            {
                if (radioHamburger.Checked == true)
                    ResetChecked();
                groupBox2.Text = "Add-on Items ($ .75/each)";
                checkBox1.Text = "Lettuce, Tomato, and Onions";
                checkBox2.Text = "Mayonnaise and Mustard";
                checkBox3.Text = "French Fries";

            }
            {
                if (radioSalad.Checked == true)
                    ResetChecked();
                groupBox2.Text = "Add-on Items ($ .25/each)";
                checkBox1.Text = "Croutons";
                checkBox2.Text = "Bacon bits";
                checkBox3.Text = "Bread sticks";


            }
            {
                if (radioSalad.Checked == true)
                    ResetChecked();
                groupBox2.Text = "Add-on Items ($ .25/each)";
                checkBox1.Text = "Croutons";
                checkBox2.Text = "Bacon bits";
                checkBox3.Text = "Bread sticks";


            }
        }
    }
}

Of course it doesn't change. The Load event of the form is raised only when the form loads. If you want to do something when the Checked property of the RadioButtons changes then you have to handle the event that is raised in that case, i.e. the CheckedChanged event of the RadioButtons. Go back to your original code and do as I instructed and it will work.

[QuestionPlease]

so how do I exactly do that do I wire the controls with the textchanged event

[jmcilhinney]

Um, you don't. You do what I told you to do:

If you want to do something when the Checked property of the RadioButtons changes then you have to handle the event that is raised in that case, i.e. the CheckedChanged event of the RadioButtons.

That's why your original methods each had a name that consisted of the name of a one of the RadioButtons combined with '_CheckedChanged'.
