Upgrading Telerik UI for ASP.NET MVC

This document describes how to upgrade the version of the Telerik UI for ASP.NET MVC helpers.

Upgrading to New Versions

To update Telerik UI for ASP.NET MVC to a new version, either:

• Use the Upgrade Project Wizard.

• Manually replace the references and files.

Using the Upgrade Project Wizard

To upgrade your project by using the Upgrade Project Wizard, follow these steps:

1. Open the Extensions->Telerik Menu or click the Update Now button as in the screenshot below to start the upgrading process.

   

2. Select the files that must be included in the update process and click Next.

   

3. Choose the project or projects you want to upgrade.

   

4. Pick an option for the EditorTemplates folder.

   

5. Create a backup.

   

6. Be careful not to overwrite any existing customized editor templates.

   

The project will be upgraded to the latest Telerik UI for ASP.NET MVC version.

Upgrading Manually

1. Replace all scripts, styles, and images that are related to Telerik UI for ASP.NET MVC with the desired version of the framework.

2. Download the desired version from the UI for ASP.NET MVC download page.

3. In the application, manually replace any references that point to the old Kendo UI scripts and styles.

   • If the scripts and styles are referenced through the Kendo UI CDN service, update the links with the new version.

     HTML

     <link rel="stylesheet" href="https://kendo.cdn.telerik.com/themes/11.0.2/default/default-main.css" />
     <script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
     <script src="https://kendo.cdn.telerik.com/2025.2.702/js/kendo.all.min.js"></script>
     <script src="https://kendo.cdn.telerik.com/2025.2.702/js/kendo.aspnetmvc.min.js"></script>

   • If the scripts and styles are referenced locally, download the JavaScript and CSS files from the Telerik website and then copying them in your project. For the detailed step-by-step procedure, refer to the Using Local Files article.

The Kendo.Mvc.dll and the required client-side resources must have identical versions.

Switching to a Developer License [Deprecated]
