Adding Angular 8 Listview
You can add the Angular 8 Listview component by using `ejs-listview` tag and the attributes used within this tag allows you to define other Listview functionalities.
- Import ListViewModule into app.module.ts file from the @syncfusion/ej2-angular-lists package.
[app.module.ts]
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 { } |
- Import the CSS styles of the Listview component.
[style.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"; |
- Add the Listview component in the template file.
[app.component.html]
<ejs-listview id="list" [dataSource]="dataSource"></ejs-listview> |
- 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' }, ]; } |
- Run the application with the following command and you should the see the below represented output of the EJ2 Angular Listview component.
ng serve --open |
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 8 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> |
