Enhancing Your ASP.NET Core Application with AJAX and Partial Views for Pagination

When you're building a web application with ASP.NET Core, one of the essential features you might need is a well-functioning pagination system. However, if your pagination causes the entire page to refresh when changing pages, it can lead to a poor user experience. In this post, we'll dive into how to elegantly implement pagination and search without page refreshes by using AJAX and Partial Views. Let's explore this together!

Understanding the Problem

Imagine you've designed a table displaying user data in your ASP.NET Core application. It works perfectly; however, every time a user clicks on a different page number, the whole page reloads. Not only does this slow down the navigation, but it disrupts the user's experience. What you really want is to change the page content dynamically without refreshing the entire page.

The Solution: Using AJAX and Partial Views

Step 1: Setting Up Your Controller

Let’s begin by modifying your existing controller to handle requests for the user data without refreshing the page. You can set up a new action that will serve up the data in a Partial View format. Here’s how your controller might look:

Why POST?: We opted for POST to encapsulate the data transfer cleanly and avoid caching issues.

Step 2: The UsersForAdminViewModel and User Retrieval Logic

Your UserService will remain intact for the pagination logic as follows:

Step 3: The Partial View Setup

Create a new Partial View (e.g., PartialName.cshtml) where you’ll only render the table rows. It might look something like this:

Step 4: The AJAX Script

To integrate the functionality without page refresh, you will need an AJAX script. Place this script in your main view or layout file, ensuring it only runs once the page is fully loaded:

Conclusion

Implementing pagination and search with AJAX in an ASP.NET Core application allows for a more seamless and enjoyable user experience. By following these steps, you can ensure that changing pages results in no reloads, maintaining the user context throughout their session. Whether you're a seasoned developer or just starting, integrating AJAX and Partial Views is a strategy every ASP.NET Core developer should consider.
