DevExtreme Angular - PivotGridDataSource Properties

This section describes properties that configure the PivotGridDataSource.

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

// ...

        },
        byKey: (key) => {
            // Retrieving a data object by key
        }
    })
});

class App extends React.Component {
    // ...
}
export default App;

fields[]

Configures pivot grid fields.

import { DxDataSourceTypes } from "devextreme-angular/ui/data-source"

Type: DxDataSourceTypes.Field

Default Value: undefined

This property 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 property. Fields with the specified area property 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
    });

If the retrieveFields property 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.

filter

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

Type:

Filter Expression

Possible variants:

Binary filter
Supported operators: "=", "<>", ">", ">=", "<", "<=", "startswith", "endswith", "contains", "notcontains".
Example:
```
[ "dataField", "=", 3 ]
```
Unary filter
Supported operators: binary operators, "!".
Example:
```
[ "!", [ "dataField", "=", 3 ] ]
```

Complex filter
Supported operators: binary and unary operators, "and", "or".
Example:

[
    [ "dataField", "=", 10 ],
    "and",
    [
        [ "anotherDataField", "<", 3 ],
        "or",

export default App;

paginate

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

Type:

Boolean

Default Value: false

Paging has the following specifics:

scrolling.mode should be "virtual".
Data should come from a remote source because other data processing operations also become remote when you enable paging.
allowExpandAll and allowSortingBySummary are ignored.
Running totals and the "absoluteVariation" and "percentVariation" summary post-processing functions are calculated only for loaded data.
Grouped items in the header filter are not paginated.
Empty records are NOT filtered out.

View Demo

remoteOperations

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

Type:

Boolean

Default Value: false

If you enable this property, the PivotGrid sends several requests to load data. At first launch, the UI component sends a request to get the data structure. It contains the following loadOptions:

JavaScript

{
    skip: 0,
    take: 20
}

NOTE

If you use local stores (ArrayStore or LocalStore) in the PivotGridDataSource, disable the remoteOperations property to ensure that usage scenarios works properly.

The server should return an array of data objects. It may contain a single object if this object reflects the entire data structure.

Subsequent requests are different and contain the following loadOptions:

JavaScript

{ 
    filter: [
        [ "dataFieldName1", "operator", "value" ],
        "and", // "or"
        [ "dataFieldName2", "operator", "value" ],
        // Filter for date fields
        // The following date components are supported:
        // year, month (from 1 to 12), day, dayOfWeek (from 0 to 6)
        // ['dateField.year', '>', '2000'],
        // "and", // "or"
        // ['dateField.dayOfWeek', '=', '4']
        // ...
    ],
    group: [
        // Group expression for numbers
        { selector: "dataFieldName1", groupInterval: 100, desc: false },
        // Group expression for dates
        { selector: "dataFieldName2", groupInterval: "year", desc: false },
        { selector: "dataFieldName2", groupInterval: "month", desc: false },
        // Group expression for strings
        { selector: "dataFieldName3", desc: true },
        // ...
    ],
    totalSummary: [
        { selector: "dataFieldName1", summaryType: "sum" }, 
        { selector: "dataFieldName2", summaryType: "min" },
        // ... 
    ],
    groupSummary: [
        { selector: "dataFieldName1", summaryType: "sum" }, 
        { selector: "dataFieldName2", summaryType: "min" },
        // ... 
    ]
}

A sorting operation executes on a back-end if you enable the remoteOperations property and set the 'scrolling.mode' property to 'virtual'. In all other cases, a sorting operation is executed locally.

Refer to the Server-Side Data Processing article for more information on how DevExtreme components communicate with the server.

retrieveFields

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

Type:

Boolean

Default Value: true

If you disable this property, the PivotGrid contains only the fields configured in the fields array. With this property enabled, these fields are accompanied by auto-generated fields, which do not belong to any area by default and are only available in the field chooser.

store

Configures the DataSource's underlying store.

Type:

Store

|

Store Configuration

|

XmlaStore

|

XmlaStore Configuration

|

Object

|

Array<Object>

This property 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 property.
