DevExtreme Angular - PivotGridDataSource API

The PivotGridDataSource is an object that provides an API for processing data from an underlying store. This object is used in the PivotGrid UI component.

import PivotGridDataSource from "devextreme-angular/ui/data-source"
jQuery
JavaScript
 $(function() { var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({ store: { // ... // Underlying store is configured here // ... }, fields: [{ area: "column", dataField: "OrderDate", dataType: "date" }, { area: "row", dataField: "ShipCity" }, { area: "data", summaryType: "count" }] }); $("#pivotGridContainer").dxPivotGrid({ dataSource: pivotGridDataSource }); });
Angular
TypeScript
HTML
 import PivotGridDataSource from "devextreme/ui/pivot_grid/data_source"; import { DxPivotGridModule } from "devextreme-angular"; // ... export class AppComponent { pivotGridDataSource: PivotGridDataSource; constructor () { this.pivotGridDataSource = new PivotGridDataSource({ store: { // ... // Underlying store is configured here // ... }, fields: [{ area: "column", dataField: "OrderDate", dataType: "date" }, { area: "row", dataField: "ShipCity" }, { area: "data", summaryType: "count" }] }); } } @NgModule({ imports: [ // ... DxPivotGridModule ], // ... })
 <dx-pivot-grid [dataSource]="pivotGridDataSource"> </dx-pivot-grid>
Vue
App.vue
 <template> <DxPivotGrid :data-source="pivotGridDataSource" /> </template> <script> import PivotGridDataSource from 'devextreme/ui/pivot_grid/data_source'; import DxPivotGrid from 'devextreme-vue/pivot-grid'; const pivotGridDataSource = new PivotGridDataSource({ store: { // ... // Underlying store is configured here // ... }, fields: [{ area: 'column', dataField: 'OrderDate', dataType: 'date' }, { area: 'row', dataField: 'ShipCity' }, { area: 'data', summaryType: 'count' }] }); export default { components: { DxPivotGrid }, data() { return { pivotGridDataSource } } } </script>
React
App.js
 import React from 'react'; import PivotGridDataSource from 'devextreme/ui/pivot_grid/data_source'; import DxPivotGrid from 'devextreme-react/pivot-grid'; const pivotGridDataSource = new PivotGridDataSource({ store: { // ... // Underlying store is configured here // ... }, fields: [{ area: 'column', dataField: 'OrderDate', dataType: 'date' }, { area: 'row', dataField: 'ShipCity' }, { area: 'data', summaryType: 'count' }] }); class App extends React.Component { render() { return ( <PivotGrid dataSource={pivotGridDataSource} /> ); } } export default App;
NOTE
If you create a PivotGridDataSource instance outside the UI component (as shown above), make sure to dispose of it when it is no longer used. If the instance is created inside the UI component, it will be disposed of automatically.
NOTE
The PivotGridDataSource is immutable. You cannot change its configuration at runtime. However, you can use its methods to manipulate it.

Properties

This section describes properties that configure the PivotGridDataSource.

Name Description
fields

Configures pivot grid fields.
filter

Specifies data filtering conditions. Cannot be used with an XmlaStore.
onChanged

A function that is executed after data is successfully loaded.
onFieldsPrepared

A function that is executed when all fields are loaded from the store and they are ready to be displayed in the PivotGrid.
onLoadError

A function that is executed when data loading fails.
onLoadingChanged

A function that is executed when the data loading status changes.
paginate

Specifies whether the PivotGridDataSource should load data in portions. Can be used only with an XmlaStore.
remoteOperations

Specifies whether the data processing operations (filtering, grouping, summary calculation) should be performed on the server.
retrieveFields

Specifies whether to auto-generate pivot grid fields from the store's data.
store

Configures the DataSource's underlying store.
NOTE

The PivotGridDataSource allows you to specify CustomStore properties in its configuration object, as shown in the following code:

jQuery
JavaScript
 var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({ load: function (loadOptions) { // Loading data objects }, byKey: function (key) { // Retrieving a data object by key } });
Angular
TypeScript
 import PivotGridDataSource from "devextreme/ui/pivot_grid/data_source"; import CustomStore from "devextreme/data/custom_store"; // ... export class AppComponent { pivotGridDataSource: PivotGridDataSource; constructor() { this.pivotGridDataSource = new PivotGridDataSource({ store: new CustomStore({ load: (loadOptions) => { // Loading data objects }, byKey: (key) => { // Retrieving a data object by key } }) }); } }
Vue
App.vue
 <script> import PivotGridDataSource from 'devextreme/ui/pivot_grid/data_source'; import CustomStore from 'devextreme/data/custom_store'; const pivotGridDataSource = new PivotGridDataSource({ store: new CustomStore({ load: (loadOptions) => { // Loading data objects }, byKey: (key) => { // Retrieving a data object by key } }) }); export default { // ... data() { return { pivotGridDataSource } } } </script>
React
App.js
 // ... import PivotGridDataSource from 'devextreme/ui/pivot_grid/data_source'; import CustomStore from 'devextreme/data/custom_store'; const pivotGridDataSource = new PivotGridDataSource({ store: new CustomStore({ load: (loadOptions) => { // Loading data objects }, byKey: (key) => { // Retrieving a data object by key } }) }); class App extends React.Component { // ... } export default App;

Methods

This section describes methods that control the PivotGridDataSource.

Name Description
collapseAll(id)

Collapses all header items of a field with the specified identifier.
collapseHeaderItem(area, path)

Collapses a specific header item.
createDrillDownDataSource(options)

Provides access to the facts that were used to calculate a specific summary value.
dispose()

Disposes of all the resources allocated to the PivotGridDataSource instance.
