Create, Edit, & Delete Multiple Records Simultaneously: ASP.NET Core & EF Core

In this video, you'll learn a practical and essential technique for any web developer: how to perform bulk Create, Edit, and Delete (CRUD) operations on multiple records within a single form, using ASP.NET Core and Entity Framework Core. We will walk through a complete, real-world example using a classic one-to-many relationship: Schools and School Achievements. You'll see exactly how to: Set up your data models with EF Core relationships. Build a dynamic frontend form that allows users to add/remove achievement fields. Efficiently handle form submission with multiple child records. Implement the backend logic to create new achievements, update existing ones, and delete records that have been removed by the user—all in one efficient operation. We specifically focus on creating and editing 5 achievements at a time for demonstration, but the principles scale up. This is a crucial skill for building user-friendly and efficient data entry interfaces. By the end, you'll have a clear understanding of the design patterns and code required to implement powerful multi-record functionality in your own projects.
