CDN Naming Convention Change

Updated on Nov 6, 2026

Environment

Product	Telerik UI for ASP.NET Core
Progress Telerik UI for ASP.NET Core version	2023.1.314

Description

I was using the following Kendo JS and CSS links before upgrading Telerik UI for ASP.NET Core:

Razor

    https://cdn.jsdelivr.net/npm/@progress/kendo-ui@2022.2.802/css/web/kendo.bootstrap-main.min.css

However, as of the latest R1 2023 SP1 release, these resources seem to be obsolete. How can I reference the themes from jsDelivr?

Solution

As of version R1 2023 SP1, the themes are available as npm packages through jsDelivr. A theme URL identifies:

• Theme version—for example, 7.0.2.
• Theme name—for example, default, bootstrap, material, and so on.
• File name—is the name of the theme.

The following example shows a jsDelivr URL for the Bootstrap theme:

Razor

    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@progress/kendo-theme-bootstrap@7.0.2/dist/all.css" />
