How to Bind Code Behind to Multiple Razor Components in Blazor Server Apps

Creating a mobile-friendly design for an existing Blazor Server application can pose a unique challenge, especially when you want to maintain shared functionality between multiple front-end components. This post explores how to effectively bind code behind to multiple Razor components, enabling you to create a cohesive user experience across both desktop and mobile platforms.

Understanding the Challenge

Imagine you have a Blazor application that currently uses .razor files alongside .razor.cs files for code-behind functionality. You want to implement two distinct front-ends—a desktop version and a mobile version—while keeping the back-end logic centralized. This leads to the question: Is it possible to use two front ends that refer to the same back end?

The straightforward answer is yes, and we will walk through the steps required to implement this solution effectively.

The Solution: Centralizing Your Code

The approach to sharing code between your Razor components involves moving away from the default code-behind structure of .razor.cs files and encapsulating this functionality into a shared class. Here’s how you can achieve this:

Step 1: Create a Base Class for the Component

Move the logic from Foo.razor.cs into a new class named FooComponent.cs. This class will act as the base class where all shared functionality will reside.

Ensure that this new class contains properties, methods, and any other logic needed for both desktop and mobile views.

Step 2: Inherit from the Base Class

Modify your Razor files: For both FooDesktop.razor and FooMobile.razor, inherit from the newly created base class FooComponent.

Step 3: Access Shared Functionality

By inheriting from FooComponent, both FooDesktop and FooMobile can now access all properties and methods defined in the base class. This means that any changes made in FooComponent will automatically reflect in both front-end components, ensuring consistency.

Benefits of This Approach

Leveraging a base class to share functionality comes with several advantages:

Code Reusability: Centralizes common code, reducing duplication and saving time when changes are necessary.

Ease of Maintenance: Having a single source of truth for your logic simplifies debugging and future enhancements.

Improved Scalability: As your application grows, you can easily extend the base class or add additional components that also inherit from it.

Conclusion

Implementing a dual front-end structure in a Blazor Server application is not only possible but can be managed effectively through proper coding practices. By creating a shared base class for your components, you can maintain a clean architecture and ensure that your desktop and mobile designs reflect the same backend functionalities.

With this approach, you’ll be able to improve both your development workflow and the user experience for your application users.
