Introduction

When developing web applications, using ASP.NET Core MVC can present challenges, especially when it comes to dynamically refreshing data displayed through ViewComponents. In this guide, we will explore how to handle the refresh of data displayed in the default view of a ViewComponent using a scenario involving job listings. We'll discuss the issue at hand and provide a step-by-step solution to successfully implement dynamic data updates in your application.

Problem Overview

Imagine you have a web page that shows a list of job cards on the left side, and the right side is dedicated to displaying details of the selected job card. Initially, the first job's details load through a ViewComponent. However, as users click on different job cards, the details should update dynamically without refreshing the entire page. In this case, you need an effective method to achieve this without any hassle.

Analyzing the Existing Implementation

Let's break down the original implementation:

HTML Structure: A Razor view containing two columns – one for job cards and another for job details.

AJAX Logic: An event listener attached to each job card which triggers an AJAX call to fetch details when clicked.

ViewComponent: Initially, the selected job's details are loaded via a ViewComponent, but the data does not refresh upon subsequent clicks.

Here’s a snippet of the relevant AJAX function:

Despite successful invocation, the ViewComponent's data doesn't refresh. You may consider employing a different approach for a cleaner solution.

Proposed Solution: Utilizing Partial Views

Taking inspiration from community suggestions, the solution is to use a partial view rather than a ViewComponent for rendering job details. This approach not only simplifies the code but also enhances performance by directly injecting HTML into the page.

Step-by-Step Implementation

Creating the Partial View:

This view will be responsible for rendering job details.

Modifying the Action Method:

Change your AJAX action method to return a partial view instead of a ViewComponent result:

Advantages of This Approach

Cleaner Code: Using partial views can lead to a more streamlined code structure.

Faster Updates: Directly injecting HTML can reduce the overhead of ViewComponent rendering.

Flexibility: Easy to manage and modify partial views without impacting other components.

Conclusion

Incorporating partial views for dynamic content updates is a powerful approach in ASP.NET Core MVC applications. This solution not only resolves the issue of refreshing job detail data but also sets a foundation for easier maintenance and scalability in your application. As you develop more complex features, consider leveraging partial views alongside AJAX calls to enhance user experience and performance.
