Building a CRUD App with Drop-Down Lists in ASP.NET Core

CRUD (Create, Read, Update, Delete) operations form the backbone of many web applications. However, handling raw text input isn't always efficient. Integrating drop-down lists within these operations enhances the user experience by providing a structured, user-friendly way to select data from related tables.

In this article, we explore how to build a robust CRUD application with ASP.NET Core, focusing on how to bind relational data to Select lists using Entity Framework Core.

Key Implementation Concepts

1. Data Binding

Learn how to use SelectList or SelectListItem to pass data from the Controller to the View via ViewBag or ViewModels.

2. Tag Helpers

Utilize the asp-for and asp-items tag helpers to automatically generate clean HTML <select> elements.

We will also cover how to maintain the selected value during the Update operation, ensuring that when a user edits a record, the drop-down correctly displays the previously saved category or foreign key.
