Changing Labels

For each order, the user selects a main course item and the application displays the associated add-on items. Then, the user can select zero or more of these add-ons.


My Question is how do I get the check boxes text to change if you will when the user selects like pizza, instead of having it show lattuce and such for hamburgers I want it to show toppings. These are the add-on's that should be displayed for humburger, pizza or salad.
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

HTML Code:

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";


        }

Firstly, 'TheChecked' is a bad name for that method. Like everything, that method should have a name that describes what it does, e.g. 'ClearAddOnSelections'.

In the CheckedChanged event handlers for your RadioButtons, you should not be doing anything at all if the Checked property of the relevant RadioButton is False. If it's True then you should call your method to clear the selections from the CheckBoxes and then set the Text of each one as appropriate. In the method that clears the CheckBoxes, there's no point testing anything or returning anything. You just need three lines: one to uncheck each CheckBox. That's it, that's all.

As for your Place Order button, the Click event handler for that is all messed up because you have got If statements inside each other. There should not be any If statements inside any other If statements. You start by declaring a variable for the main item price, the single add-on price and the total add-on price. You then use an If..ElseIf statement to test each RadioButton to see which is checked and set the main item price and single add-on price appropriately. Then you use an If statement for each CheckBox and, for each one that's checked, you add the single add-on price to the total add-on price. The total add-on price will then be zero, one, two or three times the single add-on price. Once that's done, your subtotal is the main item price plus the total add-on price.

I got the texts to change and clear.. just stuck now getting the place order button to add everything
