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/ui/pivot_grid/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
    });
});

App.js

import React from 'react';

import PivotGridDataSource from 'devextreme/ui/pivot_grid/data_source';
import DxPivotGrid from 'devextreme-react/pivot-grid';

        );

}
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.

Configuration

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";

    constructor() {
        this.pivotGridDataSource = new PivotGridDataSource({
            store: new CustomStore({
                load: (loadOptions) => {
