Question

How to bind data (Gender) from database with Radio Buttons using .Net Core, Entity Framework Core (CRUD Operations)

Prasad Raveendran · Answer

To bind data (Gender) from a database to Radio Buttons in a .NET Core application using Entity Framework Core for CRUD operations, you can follow these steps: Create a Database Table : First, ensure that you have a database table to store gender information. You can use Entity Framework Core migrations to create the table, or you can create it manually. Create a Model : Create a model class that represents the Gender entity. This class should correspond to the structure of your database table. public class Gender { public int Id { get; set; } public string Name { get; set; } } 3. DbContext Configuration : In your DbContext class, add a DbSet for the Gender model. public class ApplicationDbContext : DbContext { public DbSet Genders { get; set; } // Other DbSet properties and configuration } 4. Controller and Views : Create a controller and views for managing gender data. You can scaffold these CRUD operations using Entity Framework Core scaffolding or create them manually. 5. Create a View for Radio Buttons : In the view where you want to display radio buttons for gender selection, you can create a form to bind the data. You can use Razor Pages or Razor Views depending on your application's structure. @foreach (var gender in ViewBag.Genders) { @gender.Name } Create 6. Controller Actions : In your controller, make sure you load the gender data from the database and pass it to the view. Here's an example of how you can do this for the Create action: public IActionResult Create() { // Load genders from the database ViewBag.Genders = _context.Genders.ToList(); return View(); } [HttpPost] public IActionResult Create(int genderId) { // Use genderId to perform further operations // ... } 7. Save and Retrieve Data : When the form is submitted, you can use the selected gender ID to perform CRUD operations. For example, in the Create method, you can save the selected gender ID in the database along with other user data. This example assumes that you have set up Entity Framework Core and your database connection properly. It demonstrates how to load gender data from the database and bind it to radio buttons in a form. You can extend this pattern for CRUD operations as needed for your application.
