This article demonstrates how to enable the Progress® Telerik® UI for Blazor components in your existing Blazor app with a few mouse clicks. The supported integration is helpful if you already have a substantial app, or if you want to use the Microsoft templates to start with features like authentication and add the UI components later.
To add the Telerik UI components to your existing Blazor application, use the Convert Project Wizard. The wizard detects all installed versions of Telerik UI for Blazor and lists them in the Version combobox—this feature enables you to start your project with the desired version. To make sure you are up to date, you can also get the latest version.
The Convert Project Wizard automates a set of steps that you otherwise must perform manually.
The wizard adds the following client assets to your project:
- Telerik stylesheet
- JS Interop file
The wizard also configures the project to use the Telerik UI for Blazor components by adding the following utilities:
- Required
@using
directives to the~/_Imports.razor
file. TelerikLayout.razor
component at the root level of the DOM.- Registration of the Telerik services.
To use the Convert Project Wizard, install the Telerik UI for Blazor Visual Studio (VS) extensions. @template
To start the wizard, use either of the following options:
- In the Solution Explorer, select the Blazor app where you want to add the Telerik components (either WebAssembly, or Server-side Blazor).
- Right-click the project node and, then, select Telerik UI for Blazor > Convert to Telerik Application.
- Follow the instructions.

Alternatively, instead of the context menu, you can use the VS Extensions menu at the top:
- In the Solution Explorer, select the Blazor app where you want to add the Telerik components (either WebAssembly, or Server-side Blazor).
- Open the Extensions menu.
- Click Telerik > Telerik UI for Blazor > Convert to Telerik Application.
- Follow the instructions.

Clicking the Convert to Telerik Application button opens the Convert Project Wizard and you will go through the following steps:
This screen provides the ability to:
- Download the latest available version.
- Choose a particular version to add to the project.
- Configure additional project settings like:
- Load the required Telerik UI stylesheet and JS Interop file as static assets or from the Telerik CDN.
- Enable localization.
- Use font icons instead of the default SVG icons.
In this step, you can apply one of the available themes to your project.
You can choose to back up the project state before the conversion (in a folder called <ProjectName>_Backup>_<timestamp>
).
If necessary, the Telerik Visual Studio extension will notify you about a missing or outdated license key, and will install or update it.
When converting a project, you may encounter the following most common issues:
- The conversion wizard fails with an error screen.
- The Telerik components do not work after you run the converted project.
- An extra shared folder appears.
If you see an error screen in the wizard, make sure that you have selected the UI project in the Solution Explorer. For example, the Issue can occur in WebAssembly apps as they can include a Server and Shared projects, and only the Client project is the actual Blazor UI app that needs the Telerik components.
Some specific project settings can also cause an exception during conversion. The fastest solution is to manually configure the project for the Telerik components.
The issue can manifest in a couple of ways:
- The components have no styling.
- There are JavaScript errors that Telerik objects cannot be found.
The most common reason for this problem is a mismatch between the installed version and the actual license that you have. For example:
- Only a trial version is installed on your development machine, but you already have a commercial license, yet you never installed the commercial version.
- The wizard did not properly detect the installed version.
The cause are wrong paths to the needed web assets. To resolve this open the index file:
wwwroot/index.html
for a WebAssembly and a Hybrid Blazor app~/Pages/_Host.cshtml
for a Server-Side Blazor app using .NET 3.x or .NET 5~/Pages/_Layout.cshtml
for a Server-Side Blazor app using.NET 6
Look for the comments left by the wizard. The comments are in the <head>
near the Telerik assets and show the correct paths for a trial and commercial license.
You may get a Shared
folder that contains a TelerikLayout.razor
file at an unexpected place in the project. This can happen if a folder in the project was selected instead of the project itself when running the convert wizard.
The fix is to move the TelerikLayout.razor
file to the original Shared
folder of your project, next to the MainLayout.razor
file.
