Installing Syncfusion Pager package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

  1. Ivy library distribution package format
  2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-grids package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-grids --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-grids@ngcc package to the application.

Copied to clipboard
npm install @syncfusion/ej2-angular-grids@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

Copied to clipboard
@syncfusion/ej2-angular-grids:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Registering Pager Module

Import Pager module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-grids [src/app/app.module.ts].

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { PagerModule} from '@syncfusion/ej2-angular-grids';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
AppComponent
  ],
  imports: [
BrowserModule,
PagerModule
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Adding CSS reference

The CSS files are available in ../node_modules/@syncfusion package folder. This can be referenced in [src/styles.css] using following code..

Copied to clipboard
@import '../node_modules/@syncfusion/ej2-angular-grids/styles/material.css';
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';

Adding Pager component

Modify the template in [src/app/app.component.ts] file to render the Angular pager component. Add the Angular pager by using <ejs-pager> selector in template section of the app.component.ts file.

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-root',
  // specifies the template string for the Pager component
  template: `<ejs-pager [totalRecordsCount]='20'>
           </ejs-pager>`
})
export class AppComponent implements OnInit {
 ngOnInit(): void {
}

}

Page Size

pageSize value defines the number of records to be displayed per page. The default value for the pageSize is 12.

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Page Count

pageCount value defines the number of pages to be displayed in the pager component for navigation. The default value for pageCount is 10 and value will be updated based on totalRecordsCount and pageSize values.
