The Essential JS2 Angular Listview component is used to represent the data in interactive hierarchical structure interface across different layouts or views, that also has features such as data-binding, template, grouping, and virtualization. This article explains how to easily get started with EJ2 Listview component in Angular 11 project with minimal code.

Prerequisites

Before starting, the following tools and SDK needs to be installed in your machine to Angular 11 application.

• Node.js (latest version)
• Angular 11
• Angular CLI
• Typescript 4+
• Visual Studio Code for Editor

Installation and application creation

1. You can install Angular CLI 11 using the following command.

npm install -g @angular/cli@11.2.3

2. Create an Angular 11 application using Angular cli.

ng new angular11-app

cd angular11-app

3. Serve the Angular 11 application using following command.

ng serve 

Listen the application in localhost:4200. Your application will serve in browser. Refer the below example screenshot for Angular 11 version.

Adding Angular 11 Listview

1. After running the Angular 11 application successfully, configure the Angular Dialog in this application. Install Angular Dialog and EJ2 package using following command. 

   npm install @syncfusion/ej2-angular-lists
   
   

2. You can add the Angular 11 Listview component by using `ejs-listview` tag and the attributes used within this tag allows you to define other Listview functionalities.

3. Import ListViewModule into app.module.ts file from the @syncfusion/ej2-angular-lists package.

import { BrowserModule } from '@angular/platform-browser';

import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

import { ListViewModule } from '@syncfusion/ej2-angular-lists';

 

@NgModule({

  declarations: [

    AppComponent

  ],

  imports: [

    BrowserModule,

    ListViewModule

  ],

  providers: [],

  bootstrap: [AppComponent]

 

})

 

export class AppModule { }

4. Import the CSS styles of the Listview component.

[styles.css]

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";

@import "../node_modules/@syncfusion/ej2-angular-lists/styles/material.css";

@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

5. Add the Listview component in the template file.

[app.component.html]

<ejs-listview id="list" [dataSource]="dataSource"></ejs-listview>

6. Add the “dataSource” property in component file.

[app.component.ts]

export class AppComponent {

dataSource = [

    { id: '1', text: 'Apple' },

    { id: '2', text: 'Microsoft' },

    { id: '1', text: 'Tesla' },

    { id: '1', text: 'Google' },

    { id: '1', text: 'Twitter' },

  ];

}

7. Run the application with the following command and you should the see the below represented output of the EJ2 Angular Listview component.

ng serve 

Checklist

You can enable checkbox to select multiple items in Listview. To do so, you have to utilize the “showCheckBox” property of the Listview and set it to “true”.

[app.component.html]

<ejs-listview id="list" [dataSource]="dataSource" [showCheckBox]="true"></ejs-listview>

Now, you should see the Listivew items with checkbox enabled to them as in the following image.

Grouplist

You can group each of the Listview items into their own category by utilizing the “groupBy” property of “fields” property in Listview.

[app.component.html]

<ejs-listview id="list" [dataSource]="dataSource" [fields]="fields"></ejs-listview>

[app.component.ts]

export class AppComponent {

  dataSource = [

    { id: '1', text: 'Apple', category: "Electronics" },

    { id: '2', text: 'Samsung', category: "Electronics" },

    { id: '3', text: 'Microsoft', category: "Cloud" },

    { id: '4', text: 'Amazon', category: "Cloud" },

    { id: '5', text: 'Tesla', category: "Automotive" },

    { id: '7', text: 'Rivian', category: "Automotive" },

    { id: '8', text: 'Google', category: "Web" },

    { id: '9', text: 'Twitter', category: "Web" },

  ];

  fields: FieldSettingsModel = { groupBy: 'category' };

}

After modifying the code like above snippet, you should see the Grouplist in the browser as in the following image.

Virtualization

The Essential JS2 Listview is equipped with “Virtualization” and you can enable it by using the “enableVirtualization” property.

Virtualization is a concept of displaying only the information that is currently needed instead of loading everything into browser. This type of strategy will help Listview to load immense amount of data without sacrificing performance.

To use “Virtualization” in Angular 11 Listview you need  to import “VirtualizationService” service provider into you “app.module.ts” file.

[app.module.ts]

import { ListViewModule, VirtualizationService } from '@syncfusion/ej2-angular-lists';

 

@NgModule({

  declarations: [

    AppComponent

  ],

  imports: [

    BrowserModule,

    ListViewModule

  ],

  providers: [VirtualizationService],

  bootstrap: [AppComponent]

})

export class AppModule { }

[app.component.html]

<ejs-listview id="list" [dataSource]="dataSource" [fields]="fields" [enableVirtualization]="true"></ejs-listview>
