How To Change itemsPerPageLabel in mat-paginator in Angular 6+

Question

I am using Angular 6.0.3 with Angular Material 7.1.0, I have my paginator in a separate component (that is not the app.component). What I have tried so far:

Created separate ts file called myPagniator.ts:

import {MatPaginatorIntl} from '@angular/material';

export class MyPaginatorLabel extends MatPaginatorIntl {

  itemsPerPageLabel = 'custome_label_name'; // customize item per page label

  constructor() {
    super();
  }
}

In my app.module.ts : I imported both MatPaginatorModule, MatPaginatorIntl from Angular Material. Inside providers array of app.module.ts, I put in MyPaginatorLabel and MatPaginatorIntl.

In the component which is using Angular MatPaginator, I extends MyPaginatorLabel class and have its constructor calls super() method, still it displays default text "itemsPerPage" after all this

What have I done wrong here ?? Can someone give me a bit of hint ?

Answer 1

Create a new TypeScript file and add a function that is exported and returns a MatPaginatorIntl object.

To modify the labels and text displayed, create a new instance of MatPaginatorIntl and include it in a custom provider - Angular Material - Paginator > API

CustomPaginatorConfiguration.ts

import { MatPaginatorIntl } from '@angular/material';

export function CustomPaginator() {
  const customPaginatorIntl = new MatPaginatorIntl();

  customPaginatorIntl.itemsPerPageLabel = 'Custom_Label:';

  return customPaginatorIntl;
}

Then add it to app.module.ts:

import { MatPaginatorIntl } from '@angular/material';
import { CustomPaginator } from './app/CustomPaginatorConfiguration';

@NgModule({
  // ...
  providers: [
    { provide: MatPaginatorIntl, useValue: CustomPaginator() }
  ]
})

You can also set the setting for a particular component like:

import { CustomPaginator } from './CustomPaginator';
import { MatPaginatorIntl } from '@angular/material';
/**
 * @title Paginator
 */
@Component({
  selector: 'your_component',
  templateUrl: 'your_component.html',
  providers: [
    { provide: MatPaginatorIntl, useValue: CustomPaginator() }  // Here
  ]
})
