DevExtreme Angular - Add DevExtreme to an ASP.NET Core Angular Application

This article describes how to create an ASP.NET Core Angular application and add a DevExtreme widget to it. Before you begin, make sure that you have Visual Studio 2017 or higher and .NET Core 2.0 SDK installed.

1. Open Visual Studio 2017 and create a new ASP.NET Core Angular application using the ASP.NET Core Web Application template.

2. Open the package.json file and add the devextreme and devextreme-angular packages to the devDependencies section.

   "devDependencies": {
       ...
       "devextreme": "17.2.18",
       "devextreme-angular": "17.2.18"
   }

   Save the changes and wait until Visual Studio has downloaded the dependencies.

3. Open the webpack.config.vendor.js file, register the required .css files and then build the application to update the vendor bundle.

   const nonTreeShakableModules = [
       ...
       'devextreme/dist/css/dx.common.css',
       'devextreme/dist/css/dx.light.css'
   ];

4. Open the ClientApp\app\app.shared.module.ts file and import individual DevExtreme modules or the entire DevExtreme. Add the imported modules to the imports array:

   // Imports the entire DevExtreme
   import { DevExtremeModule } from 'devextreme-angular'; 
   
   // Imports a separate module
   // import { DxDataGridModule } from 'devextreme-angular'; 
   
   @NgModule({ 
       ... 
       imports: [ 
           ... 
           DevExtremeModule,
           // DxDataGridModule,
           ... 
       ] 
   })

5. Open the Views\Home\Index.cshtml file and remove the asp-prerender-module attribute from the <app> element. This disables server-side rendering, which is currently not supported by DevExtreme.

6. Open the ClientApp\app\components\fetchdata\fetchdata.component.html file and replace the table in it with the following code, which creates the DevExtreme DataGrid widget and binds it to sample data already provided by the FetchDataComponent:

   <dx-data-grid [dataSource]="forecasts"></dx-data-grid>

7. Run the application and when it has been loaded, navigate to the Fetch data page to view the DataGrid.
