How to use ajax in visual studio 2022 asp net core 5 0 mvc


ASP.NET is a popular programming language used for building web applications. It provides a powerful for developing dynamic and interactive websites. One of the key features of ASP.NET is its ability to handle asynchronous requests AJAX (Asynchronous JavaScript and XML).

What is AJAX?

AJAX is a technique that allows web pages to be updated asynchronously by exchanging data with a web behind the scenes. This means that of reloading the entire web page, only a portion of it can be updated, resulting in a smoother and more responsive user experience.


To use AJAX in ASP.NET, you need to include the necessary JavaScript libraries and make use of the built-in AJAX features provided by the ASP.NET framework.

Step 1: Setting up Visual Studio 2022

Before we can start using AJAX in ASP.NET, we need to set up our development environment. Make sure you have Visual Studio 2022 on your machine. If not, you can download it from the official Microsoft .

Step 2: Creating an ASP.NET Core 5.0 MVC Project

Once you have Visual Studio 2022 installed, open it and create a new ASP.NET Core 5.0 MVC project. This will provide us with a basic structure for our web application.

// ASP.NET code example
public  Index()
    return View();

Step 3: Adding AJAX Libraries

To use AJAX in our ASP.NET project, we need to include the necessary JavaScript libraries. In Visual Studio 2022, you can easily add these libraries using the NuGet manager.

Step 4: Implementing AJAX Functionality

Now that we have set up our project and added the required libraries, we can start implementing AJAX functionality in our web application. Let's say we want to load some data from the server without refreshing the entire page.

// ASP.NET code example
    url: "/Home/GetData",
    type: "GET",
    success: function (data) {
        // Update the UI with the received data

In the above example, we are making an AJAX request to the server to fetch data from the “GetData” action method in the “HomeController”. Once the data is received, we update the UI by setting the HTML content of an element with the id “result” to the received data.

Step 5: Handling AJAX Requests on the Server

To handle AJAX requests on the server side, we need to create an action method in our controller that will return the requested data. Let's modify our “HomeController” to include a “GetData” action method.

// ASP.NET code example
public IActionResult GetData()
    // Fetch data from the database or any other source
    var data = "This is the data fetched from the server";

    return Content(data);

In the above example, we are fetching some data from a database or any other source and returning it as a plain text using the “Content” method.


AJAX is a powerful feature of ASP.NET that allows us to create dynamic and interactive web applications. By using AJAX, we can update specific parts of a web page without reloading the entire page. This results in a better user experience and performance. By following the steps outlined in this article, you can easily incorporate AJAX functionality into your ASP.NET projects.
