DevExtreme Angular - PivotGridDataSource Properties

This section describes options that configure the PivotGridDataSource.

NOTE

The PivotGridDataSource allows specifying CustomStore options 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
                }
            })
        });
    }
}

fields[]

Configures pivot grid fields.

Type:

Array<Object>

Default Value: undefined

This option accepts an array of objects where each object configures a single field. Each pivot grid field must be associated with a data field using the dataField option. Fields with the specified area option are displayed in the pivot grid; other fields' headers are displayed in the field chooser.

jQuery
JavaScript
$(function() {
    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        // ...
        fields: [{
            dataField: "region",
            area: "row"
        }, {
            dataField: "date",
            dataType: "date",
            area: "column"
        }, {
            dataField: "sales",
            summaryType: "sum",
            area: "data"
        }]
    });

    $("#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({
            // ...
            fields: [{
                dataField: "region",
                area: "row"
            }, {
                dataField: "date",
                dataType: "date",
                area: "column"
            }, {
                dataField: "sales",
                summaryType: "sum",
                area: "data"
            }]
        });
    }
}

@NgModule({
    imports: [
        // ...
        DxPivotGridModule
    ],
    // ...
})
<dx-pivot-grid
    [dataSource]="pivotGridDataSource">
</dx-pivot-grid>

If the retrieveFields option is true, fields configured in the fields array are accompanied by auto-generated fields that do not belong to any area. However, a user can move them to any area using the field chooser.

See Also

retrieveFields

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

Type:

Boolean

store

Configures the DataSource's underlying store.

Type:

Store

|

Store Configuration

|

XmlaStore

XmlaStore Configuration

|

Array<Object>

Object

This option accepts one of the following:

  • Store instance
    An XmlaStore, ArrayStore, LocalStore, ODataStore, or CustomStore instance.

  • Store configuration object
    An XmlaStore, ArrayStore, LocalStore, or ODataStore configuration object. Make sure to set the type option.

  • Array
    Assigning an array to the store option automatically creates an ArrayStore in the PivotGridDataSource.

    var pivotGridDataSource = new DevExpress.data.PivotGridDataSource({
        store: new DevExpress.data.XmlaStore({
