🍕 Pizza Project

A sleek, dark-themed Windows Forms desktop app for building and pricing a custom pizza order in real time.

---

📖 Overview

Pizza Project is a C# Windows Forms application that simulates a pizza ordering counter. Users pick a size, crust type, and toppings, choose whether they're eating in or taking out, and watch the Order Summary panel and total price update instantly as they change their selections. When ready, they confirm the order with a single click, or reset the form to start over.

🚀 Getting Started

1. Install Visual Studio (2019 or later recommended) with the .NET desktop development workload.
2. Clone or download this repository.
3. Open Pizza_Project.sln in Visual Studio.
4. Press F5 (or click Start) to build and run the application.
5. The Pizza Order window will open, ready to build a pizza.

No external packages or NuGet installs are required — the project only relies on standard .NET Framework libraries.

🎯 Learning Objectives

This project demonstrates core Windows Forms and C# fundamentals, including:

• Event-driven programming with CheckedChanged and Click event handlers
• Working with RadioButtons for mutually exclusive choices (size, crust, eat-in/take-out)
• Working with CheckBoxes for multi-select options (toppings)
• Grouping related controls with GroupBoxes
• Displaying dynamic values with Labels
• Using a PictureBox to display an embedded image resource
• Reading control metadata via the Tag property to drive calculations
• Structuring UI update logic into small, single-purpose methods
• Basic form state management (enabling/disabling controls, resetting to defaults)
• Light custom UI styling using FlatStyle, FlatAppearance, and the Paint event

---

💡 Code Highlights

• Dynamic price calculation — each radio button and checkbox stores its price in its Tag property, which is summed up (GetSelectedSizePrice, CalculateToppingsPrice, GetSelectedCrustPrice) to compute the total in CalculateTotalPrice().
• Live order summary updates — dedicated methods (UpdateSize, UpdateToppings, UpdateCrust, UpdateWhereToEat) keep the summary labels in sync with the user's current selections.
• Order confirmation flow — btnOrderPizza_Click shows a confirmation dialog, then a success message, and locks the form's controls once an order is placed.
• Reset functionality — ResetForm() restores every group box, radio button, and checkbox back to its default selection in one call.
• Custom-styled toggle controls — checkboxes and radio buttons are switched to FlatStyle.Flat at runtime with custom border, hover, and checked colors so they match the app's dark theme.
• Hover and selection color feedback — MouseEnter/MouseLeave and CheckedChanged handlers change a control's text color to reflect whether it's currently hovered or selected.
• Owner-drawn accents — a Paint event handler draws a thin accent underline beneath each group box's title for extra visual polish.
