Output

No output will be shown on the page. The code-behind file contains the logic for the component.

Explanation

Blazor code-behind files are used to separate the component's markup and code logic. The code-behind file contains the C# code that handles the component's functionality and can be included in a separate file from the markup.

This separation of concerns allows for cleaner and more maintainable code, making it easier to manage and update larger components.

Use

Code-behind files can be added to a component by adding a .cs file with the same name as the .razor file, and inheriting from ComponentBase. Code-behind files can be used to handle logic such as data access, event handling, and other component functionality.

Important Points

• Code-behind files separate the component's logic from its markup
• Code-behind files can be added by adding a .cs file with the same name as the .razor file
• Code-behind files can handle functionality such as data access and event handling

Summary

Blazor code-behind files are a valuable tool for separating component markup and logic. They allow for cleaner and more maintainable code, and can handle a wide range of component functionality. Consider using code-behind files when working on larger components.
