First Steps on VS for Windows

Welcome to the First Steps on Windows guide on getting started with Progress® Telerik® UI for ASP.NET Core with Visual Studio!

The guide creates a use-case scenario which demonstrates how to start working with the suite and implements the Kendo UI DatePicker for ASP.NET Core in your project by using the Telerik UI DatePicker HtmlHelper or TagHelper. For its purposes, the guide uses Visual Studio for Windows 2019.

To configure an ASP.NET Core web application to use UI for ASP.NET Core, you can use either of the following approaches:

To get up and running with the project:

  1. Download the controls
  2. Meet the requirements
  3. Create the ASP.NET Core application
  4. Add the UI for ASP.NET Core NuGet package
  5. Add reference to Kendo.Mvc.UI
  6. Include the Telerik UI for ASP.NET Core client-side resources

Meeting the Requirements

Follow the instructions from the official .NET Core documentation site.

Creating the Application

  1. Open Visual Studio for Windows 2019 and select Create a New Project.
  2. Select ASP.NET Core Web Application and click Next.
  3. Set a name and location for the project and click Create.
  4. Select Web Application (Model-View-Controller) and click Create.

Adding the NuGet Package

  1. Open the NuGet Package Manager.

    Locating and opening the NuGet package manager menu

  2. Add a new package source to

    Adding the new NuGet source dialog

  3. From the package source drop-down, select Telerik Source and add your credentials ( email and password) as prompted.

    Adding the credentials and authenticating for NuGet

  4. Click the Browse tab and search for Telerik.UI.for.AspNet.Core to install it. As a result, a line similar to <PackageReference Include="Telerik.UI.for.AspNet.Core" Version="2020.2.617" /> is added to your .csproj file.

    Selecting and installing the NuGet package

Adding reference to Kendo.Mvc.UI

  1. Open the Startup.cs file and register the Kendo UI services in the ConfigureServices method.

    public void ConfigureServices(IServiceCollection services)
        // Add the Kendo UI services to the services container.
  2. Import the Kendo.Mvc.UI namespace in ~/Views/_ViewImports.cshtml through @using Kendo.Mvc.UI. If you intend to use the Telerik UI ASP.NET Core Tag Helpers, add them with @addTagHelper *, Kendo.Mvc.

    @using MyASPNETCoreProject
    @using MyASPNETCoreProject.Models
    @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
    @addTagHelper *, Kendo.Mvc
    @using Kendo.Mvc.UI

Including the Telerik UI for ASP.NET Core client-side resources

  1. Include the client-side resources.

    • The CDN links and/or package versions have to point to the same UI for ASP.NET Core version which your project references.
    • The Kendo UI scripts have to be placed after jQuery.

    7.1 Go to ~\Views\Shared\_Layout.cshtml and add the theme of your choice to the <head> of the document. Since the Microsoft project uses Bootstrap, you can use the Kendo UI SASS Bootstrap v4 theme to match it.

    7.2 The Microsoft ASP.NET Core Web Application template comes with a jQuery script reference at the end of _Layout.cshtml file. Find it and remove it. The Kendo UI script files required by UI for ASP.NET Core must be loaded in the <head> tag after the jQuery script.

    7.3 Copy and paste the scripts from the snippet bellow to the <head> tag in the _Layout. The content of the <head> tag with the theme file and the script files included should look as shown in the snippet below. kendo.all.min.js and kendo.aspnetmvc.min.js script files have to be loaded after the jquery.min.js script. jQuery should be loaded only once in the <head> tag. Make sure there are no duplicate references elsewhere in the _Layout.

    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - TelerikAspNetCoreApp</title>
    <link href="" rel="stylesheet" type="text/css" />
    <script src=""></script>
    <script src=""></script>
    <script src=""></script>
  2. Use a Kendo UI widget by adding the snippet from the following example to ~/Views/Home/Index.cshtml.

        <div class="text-center">
            <h2>Kendo UI DatePicker</h2>
        <div class="text-center">
            <h2>Kendo UI DatePicker</h2>
            <kendo-datepicker name="my-picker"/>

    As a result, the following sample page is created.
