Configure a Visual Studio Project

  • 4 minutes to read

You can use a DevExtreme project template to create a new project or add DevExtreme to an existing project.

Create a New Project

DevExtreme-based ASP.NET Core controls ship with the DevExtreme v23.1 ASP.NET Core Application project template. The template includes all server-side and client-side resources required for the controls, and demonstrates how to configure the DataGrid control.

The steps below describe how to use this project template.

  1. Click Create a new project on Visual Studio’s start page, select the DevExtreme v23.1 ASP.NET Core Application template, and click Next.

    Project Templates

  2. In the Configure your new project window, specify the project name and location, and click Create.

  3. In the Create a new DevExtreme v23.1 ASP.NET Core Application window, specify project settings:

    • ASP.NET Core version
    • application type: Razor Pages or MVC Views
    • layout:

      • Bootstrap - Creates a lightweight application based on the Bootstrap starter template.
      • Material - Creates a responsive application that has a navigation layout based on the Drawer control and is styled with a custom theme using color swatches. Refer to this blog post for more information.

    Project Settings

  4. Click Create. Visual Studio creates a project with the DataGrid control. You can also add other controls to a project.

Add DevExtreme to an Existing Project

To configure an existing project to use DevExtreme-based controls, add DevExtreme resources to the project and set up a layout (complete project configuration).

Add DevExtreme Resources

  1. Open your project in Visual Studio (see supported versions).

  2. Right-click the project in the Solution Explorer window and select the Add DevExtreme to the Project command in the menu.

    Context Menu Item

  3. In the invoked dialog box, click OK.

    Confirmation Dialog

    It takes a few seconds for Visual Studio to complete the following operations:

    • Server-side packages are added to the References section: DevExtreme.AspNet.Core, DevExtreme.AspNet.Data.
    • Client-side resources are added to the wwwroot folder: css\devextreme, js\devextreme.
    • The following project files are modified: Startup.cs (for .NET 3.1 or .NET 5.0), Program.cs (for .NET 6.0), _ViewImports.cshtml, NuGet.config.
    • The _DevExtremeLayout.cshtml file is created (see below to know how to use it).

    This process is logged in the Output window.

Complete the Project Configuration


To complete project configuration, make sure that client-side resources are linked in the project. You can use the DevExtreme layout file where the resources are already linked or link the resources by yourself.

Use the DevExtreme Layout File

The DevExtreme layout file (_DevExtremeLayout.cshtml) is added to the project when you click the Add DevExtreme to the Project menu command. This file contains links to all the client-side resources.

To use this layout, go to the _ViewStart.cshtml file (located in the Pages or View/Shared folder) and change _Layout to _DevExtremeLayout.

    Layout = "_DevExtremeLayout";


Use this approach if you add DevExtreme to a new ASP.NET Core project. If you have a customized project, link the resources in your project’s layout as described below.

Resources are usually linked in a project’s layout - the _Layout.cshtml file located in the Views/Shared folder (for MVC projects) or Pages folder (for Razor Pages).

Modify this file as follows:

  1. Add the following CSS and script links to the <head> section:

        @* Uncomment to use the HtmlEditor control *@
        @* <script src=""></script> *@
        @* Uncomment to use the Gantt control *@ 
        @*<link href="~/css/devextreme/dx-gantt.css" rel="stylesheet" />*@
        @* Uncomment to use the Diagram control *@
        @*<link href="~/css/devextreme/dx-diagram.css" rel="stylesheet" />*@
        <link href="~/css/devextreme/dx.light.css" rel="stylesheet" />
        @* Uncomment to use the Gantt control *@ 
        @*<script src="~/js/devextreme/dx-gantt.js"></script>*@
        @* Uncomment to use the Diagram control *@
        @*<script src="~/js/devextreme/dx-diagram.js"></script>*@
        <script src="~/js/devextreme/jquery.js"></script>
        @* Uncomment to use Globalize for localization *@
        @*<script src="~/js/devextreme/cldr.js"></script>*@
        @*<script src="~/js/devextreme/cldr/event.js"></script>*@
        @*<script src="~/js/devextreme/cldr/supplemental.js"></script>*@
        @*<script src="~/js/devextreme/cldr/unresolved.js"></script>*@
        @*<script src="~/js/devextreme/globalize.js"></script>*@
        @*<script src="~/js/devextreme/globalize/message.js"></script>*@
        @*<script src="~/js/devextreme/globalize/number.js"></script>*@
        @*<script src="~/js/devextreme/globalize/currency.js"></script>*@
        @*<script src="~/js/devextreme/globalize/date.js"></script>*@
        @* Uncomment to enable client-side export *@
        @*<script src="~/js/devextreme/jszip.js"></script>*@
        <script src="~/js/devextreme/dx.all.js"></script>
        @* Uncomment to provide geo-data for the VectorMap control *@
        @*<script src="~/js/devextreme/vectormap-data/world.js"></script>*@
        <script src="~/js/devextreme/aspnet/dx.aspnet.mvc.js"></script> 
        <script src="~/js/devextreme/aspnet/"></script>
  2. If the layout file contains jQuery links that were added earlier (they may be placed in the <environment> containers), then remove them.

    <!-- Remove the jQuery links below -->
    <environment names="Development">
        <script src="~/lib/jquery/dist/jquery.js"></script>
    <environment names="Staging,Production">
        <script src=""></script>


You can also apply bundling and minification to static resources as described in the following article: Bundle and minify static assets in ASP.NET Core.

Your project can now use DevExtreme ASP.NET Core controls. Refer to Add Controls to a Project for more information.
