Access data from a Blazor component

Engaging websites need to display dynamic content that might change all the time. Learning how to obtain data from a dynamic source, such as a database or web service, is a fundamental technique in web development.

Suppose you’re working for a pizza delivery firm on its updated customer-facing website. You have a range of webpages laid out and designed as Blazor components. Now, you want to populate those pages with information about pizzas, toppings, and orders that you want to obtain from a database.

In this unit, you learn how to access data and render it within HTML markup for display to the user.

Creating a registered data service

If you want to create a dynamic website that shows changing information to users, you must write code to get that data from somewhere. For example, suppose you have a database that stores all the pizzas your company sells. Because the pizzas are always changing, it’s a bad idea to hardcode them into the website HTML. Instead, use C# code and Blazor to query the database, and then format the details as HTML so that the user can pick their favorite.
