## Overview

This is a small Windows Forms inventory-entry application. A user opens the form, enters product details, and adds a validated product to an in-memory list displayed in a grid; format errors appear in message dialogs. The sampled code shows no database or persistence layer. The form’s controls are defined in the designer file, while event handling, validation, list updates, and error handling are in Inventory.cs.

Main entry points: [`InventoryProject/Inventory.cs`](https://github.com/lamar101214/inventoryproject/blob/master/InventoryProject/Inventory.cs) (Inventory form), [`InventoryProject/Inventory.Designer.cs`](https://github.com/lamar101214/inventoryproject/blob/master/InventoryProject/Inventory.Designer.cs) (Entry controls), [`InventoryProject/Program.cs`](https://github.com/lamar101214/inventoryproject/blob/master/InventoryProject/Program.cs) (Application entry), [`InventoryProject/NumberFormatExceptions.cs`](https://github.com/lamar101214/inventoryproject/blob/master/InventoryProject/NumberFormatExceptions.cs) (Format exceptions)
