ErrorProvider Project - Data Validation

This project is a simple C# Windows Forms application designed to demonstrate how to use the ErrorProvider component to validate user input and display error messages when required fields are left empty.

Features

• Real-time Validation: The application validates input as soon as the user leaves a field (using the Validating event).
• Visual Feedback: Displays an error icon next to the field that contains invalid data.
• User Experience: Clearly indicates which mandatory fields need to be filled.

Key Components

The following components are implemented in Form1.cs:

• ErrorProvider: Manages the display of error icons and messages.
• txtFirstName_Validating: Ensures the First Name field is not empty.
• txtLastName_Validating: Ensures the Last Name field is not empty.
• button1_Click: Resets the form by clearing all text fields.

How to Run

1. Open the solution file ErrorProvider.slnx or the project ErrorProvider.csproj in Visual Studio.
2. Ensure the Target Framework is set to v4.7.2.
3. Build and run the project.

Technical Specifications
