Paging is used to load data in portions, which improves the UI component's performance on large datasets. Paging is enabled by default. You can control it with the paging object. Use this object's pageIndex and pageSize properties of to specify the initial page and the number of rows on a page.
jQuery
JavaScript
$(function () { $("#dataGridContainer").dxDataGrid({ // ... paging: { pageSize: 15, pageIndex: 1 // Shows the second page } });});Angular
HTML
TypeScript
<dx-data-grid> <dxo-paging [pageSize]="15" [pageIndex]="1"> <!-- Shows the second page --> </dxo-paging></dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";// ...export class AppComponent { // ...}@NgModule({ imports: [ // ... DxDataGridModule ], // ...})Vue
App.vue
<template> <DxDataGrid ... > <DxPaging :page-size="15" :page-index="1" /> <!-- Shows the second page --> </DxDataGrid></template><script>import 'devextreme/dist/css/dx.light.css';import DxDataGrid, { DxPaging} from 'devextreme-vue/data-grid';export default { components: { DxDataGrid, DxPaging }}</script>React
App.js
import React from 'react';import 'devextreme/dist/css/dx.light.css';import DataGrid, { Paging} from 'devextreme-react/data-grid';class App extends React.Component { render() { return ( <DataGrid ... > <Paging defaultPageSize={15} defaultPageIndex={1} /> {/* Shows the second page */} </DataGrid> ); }}export default App;When working with small datasets, you can disable paging by setting the paging.enabled property to false.
jQuery
JavaScript
$(function () { $("#dataGridContainer").dxDataGrid({ // ... paging: { enabled: false } });});Angular

<dx-data-grid ... > <dxo-paging [enabled]="false"></dxo-paging></dx-data-grid>

This section describes how to configure the pager, a component that allows users to navigate through pages and change their size at runtime. The pager consists of the page navigator and several optional elements: the page size selector, navigation buttons, and page information.
Set the showNavigationButtons and the showPageSizeSelector properties to true to show the navigation buttons and the page size selector. The set of available page sizes depends on how large the data source is. You can change it using the allowedPageSizes property.
jQuery
JavaScript
$(function () { $("#dataGridContainer").dxDataGrid({ // ... pager: { showPageSizeSelector: true, allowedPageSizes: [10, 20, 50], showNavigationButtons: true } });});Angular
HTML
TypeScript
<dx-data-grid ... > <dxo-pager [showPageSizeSelector]="true" [allowedPageSizes]="[10, 20, 50]" [showNavigationButtons]="true"> </dxo-pager></dx-data-grid>

You can change the default text by specifiyng the infoText.
jQuery
JavaScript
$(function () { $("#dataGridContainer").dxDataGrid({ // ... pager: { showInfo: true, infoText: "Page #{0}. Total: {1} ({2} items)" } });});Angular

API
Call the pageCount() method to get the total page count.
jQuery
JavaScript
var totalPageCount = $("#dataGridContainer").dxDataGrid("instance").pageCount();Angular
TypeScript
import { ..., ViewChild } from "@angular/core";import { DxDataGridModule, DxDataGridComponent } from "devextreme-angular";// ...export class AppComponent { @ViewChild(DxDataGridComponent, { static: false }) dataGrid: DxDataGridComponent; // Prior to Angular 8 // @ViewChild(DxDataGridComponent) dataGrid: DxDataGridComponent; getTotalPageCount () { this.dataGrid.instance.pageCount(); }}@NgModule({ imports: [ // ... DxDataGridModule ], // ...})Vue

They can also be called without arguments, in which case, they return the index and size of the current page.
jQuery
JavaScript
$("#dataGridContainer").dxDataGrid("instance").pageSize(8);JavaScript
var goToLastPage = function (dataGridInstance) { dataGridInstance.pageIndex(dataGridInstance.pageCount() - 1);}Angular
