Using DevExtreme Components With the ABP Framework

Hi, in this step by step article, I will show you how to integrate DevExtreme components into ABP Framework-based applications.


(A screenshot from the example application developed in this article)

Create the Project

ABP Framework offers startup templates to get into the business faster. We can download a new startup template using ABP CLI:

abp new DevExtremeSample

After the download is finished, open the solution in the Visual Studio (or your favorite IDE):


Run the DevExtremeSample.DbMigrator application to create the database and seed initial data (which creates the admin user, admin role, related permissions, etc). Then we can run the DevExtremeSample.Web project to see our application working.

Default admin username is admin and password is 1q2w3E*

Install DevExtreme

You can follow this documentation to install DevExpress packages into your computer.

Don't forget to add "DevExpress NuGet Feed" to your Nuget Package Sources.

Adding DevExtreme NuGet Packages

Add the DevExtreme.AspNet.Core NuGet package to the DevExtremeSample.Application.Contracts project.

Install-Package DevExtreme.AspNet.Core

Add the DevExtreme.AspNet.Data package to your DevExtremeSample.Web project.

Install-Package DevExtreme.AspNet.Data

Adding DevExtreme NPM Dependencies

Open your DevExtremeSample.Web project folder with a command line and add devextreme and devextreme-aspnet-data NPM packages:

npm install devextreme
npm install devextreme-aspnet-data

Adding Resource Mappings

The devextreme and devextreme-aspnet-data NPM packages are saved under node_modules folder. We need to move the needed files in our wwwroot/libs folder to use them in our web project. We can do it using the ABP client side resource mapping system.

Open the abp.resourcemapping.js file in your DevExtremeSample.Web project and add the following definitions to inside mappings object.

"@node_modules/devextreme/dist/**/*": "@libs/devextreme/",
"@node_modules/devextreme-aspnet-data/js/": "@libs/devextreme/js/"

The final abp.resourcemapping.js file should look like below:

module.exports = {
  aliases: {},
  mappings: {
    "@node_modules/devextreme/dist/**/*": "@libs/devextreme/",
    "@node_modules/devextreme-aspnet-data/js/": "@libs/devextreme/"

Open your DevExtremeSample.Web project folder with a command line and run the gulp command. This command will copy the needed library files into the ``/wwwroot/libs/devextreme/` folder.


You can see devextreme folder inside the wwwroot/libs:


Adding DevExtremeStyleContributor

We will add DevExtreme CSS files to the global bundle by creating a bundle contributor.

Create a Bundling folder in the DevExtremeSample.Web project and a DevExtremeStyleContributor.cs file with the following content:

using System.Collections.Generic;
using Volo.Abp.AspNetCore.Mvc.UI.Bundling;

namespace DevExtremeSample.Web.Bundling
    public class DevExtremeStyleContributor : BundleContributor
        public override void ConfigureBundle(BundleConfigurationContext context)

You can choose another theme than the light theme. Check the /libs/devextreme/css/ folder and the DevExtreme documentation for other themes.

Open your DevExtremeSampleWebModule.cs file in your DevExtremeSample.Web project and add following code into the ConfigureServices method:

Configure<AbpBundlingOptions>(options =>

Adding DevExtremeScriptContributor

We can not add DevExtreme js packages to Global Script Bundles, just like done for the CSS files. Because DevExtreme requires to add its JavaScript files into the <head> section of the HTML document, while ABP Framework adds all JavaScript files to the end of the <body> (as a best practice).

Fortunately, ABP Framework has a layout hook system that allows you to add any code into some specific positions in the HTML document. All you need to do is to create a ViewComponent and configure the layout hooks.

Let's begin by creating a DevExtremeScriptContributor.cs file in the Bundling folder by copying the following code inside it:

using System.Collections.Generic;
using Volo.Abp.AspNetCore.Mvc.UI.Bundling;
using Volo.Abp.AspNetCore.Mvc.UI.Packages.JQuery;
using Volo.Abp.Modularity;

namespace DevExtremeSample.Web.Bundling
    public class DevExtremeScriptContributor : BundleContributor
        public override void ConfigureBundle(BundleConfigurationContext context)

As you see, the DevExtremeScriptContributor depends on JQueryScriptContributor which adds JQuery related files before the DevExpress packages (see the bundling system for details).

Create DevExtremeJsViewComponent

Create a new view component, named DevExtremeJsViewComponent inside the /Components/DevExtremeJs folder of the Web project, by following the steps below:

  1. Create a DevExtremeJsViewComponent class inside the /Components/DevExtremeJs (create the folders first):
using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc;

namespace DevExtremeSample.Web.Components.DevExtremeJs
    public class DevExtremeJsViewComponent : AbpViewComponent
        public IViewComponentResult Invoke()
            return View("/Components/DevExtremeJs/Default.cshtml");
  1. Create Default.cshtml file in the same folder with the following content:
@using DevExtremeSample.Web.Bundling
@addTagHelper *, Volo.Abp.AspNetCore.Mvc.UI.Bundling

<abp-script type="typeof(DevExtremeScriptContributor)" />

Your final Web project should be like the following:


  1. Now, we can add this view component to <head> section by using the layout hooks.

Open your DevExtremeSampleWebModule.cs file in your DevExtremeSample.Web project and add following code into the ConfigureServices method:

Configure<AbpLayoutHookOptions>(options =>
        LayoutHooks.Head.Last, //The hook name
        typeof(DevExtremeJsViewComponent) //The component to add

Known Issue: Uncaught TypeError: MutationObserver.observe: Argument 1 is not an object.

This issue does exist in the ABP Framework v3.0 and earlier versions. If you are using ABP Framework v3.1 or a later version, you can skip this section.

When you run your *.Web project, you will see an exception (Uncaught TypeError: MutationObserver.observe: Argument 1 is not an object.) at your console.

To fix that issue, download this file abp.jquery.js and replace with the wwwroot/libs/abp/jquery/abp.jquery.js file of your Web project.


The installation step was done. You can use any DevExtreme component in your application.

Example: A button and a progress bar component:


This example has been created by following this documentation.

The Sample Application

We have created a sample application with Tree List and Data Grid examples.

The Source Code

You can download the source code from here.

Data Grid

You can see the full working example of Data Grid.

Tree List

You can see the full working example of Tree List.

Additional Notes

Data Storage

I've used an in-memory list to store data for this example, instead of a real database. Because it is not related to DevExpress usage. There is a SampleDataService.cs file in Data folder at .Application.Contracts project. All the data is stored here.

JSON Serialization

You can see some JsonProperty attributes on the DTO properties. I use these attributes because DevExtreme example expects PascalCase property names in the serialized JSON that is sent to the client. But ABP Framework & ASP.NET Core conventionally uses camelCase property names on JSON serialization. Adding these JsonProperty attributes ensures that the related properties are serialized as PascalCase.

DevExtreme Components vs Application Service Methods

ABP Framework conventionally converts application services to API Controllers. For example, see the application service below:

public class OrderAppService : DevExtremeSampleAppService, IOrderAppService
    public async Task<LoadResult> GetOrdersAsync(DataSourceLoadOptions loadOptions)

    public async Task<Order> InsertOrder(string values)

You can use these service methods for your DevExtreme components as shown below:

            .DataSource(d => d.Mvc()
                .Controller("Order") // Application Service Name without 'AppService'
                .LoadAction("GetOrders") // Method Name without 'Async'


In this article, I've explained how to use DevExtreme components in your application. ABP Framework is designed so that it can work with any UI library/framework.
