Using CDN

The Kendo UI client-side resources like JavaScript files and CSS files are available online through the Kendo CDN service. Including the client-side resources in your project is essential because the Telerik UI helpers are wrappers over the Kendo UI widgets.

Only the official Kendo UI releases and serviced packs are uploaded to the CDN. Internal builds are not available on the CDN.

To access the Kendo UI CDN services, you can use either the HTTP or the HTTPS protocol with any of the following CDN services:

  • (a cookieless CDN service)

Understanding the CDN Structure

The URLs of the Telerik CDN have the following structure:


In the URL above, you must replace VERSION and FILENAME with the client-side resource that you need and its version. For example, to load version 2022.2.621 of the minified Kendo UI scripts and the related CSS files, use these URLs:


If you prefer the HTTP protocol, replace https with http in the URLs above.

Using the CDN in Your Project

Replace the Kendo UI version from the following code snippets with the version of the product you are using—for example, 2022.2.621.

  1. Open the layout of the application. By default, it is ~\Views\Shared\_Layout.cshtml.

  2. To add the Bootstrap theme files, insert a link tag within the head tag of the layout and include the style file or files.

        <link href="" rel="stylesheet" type="text/css" /> 
  3. To add the JavaScript files, insert a script tag and include kendo.all.min.js and kendo.aspnetmvc.min.js after the jQuery script.

        <script src=""></script>
        <script src=""></script>
