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:

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.

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.

  • 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.
