React PivotGrid Methods

This section describes the methods that can be used to manipulate the PivotGrid UI component.

beginUpdate()

Prevents the UI component from refreshing until the endUpdate() method is called.

The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

Object

The Chart to be bound to the PivotGrid.
Accepts the Chart's instance, jQuery element or container selector.

integrationOptions:

Object

The Chart's configuration.

Object structure:

Name	Type	Description
alternateDataFields	Boolean	Default Value: true. Specifies whether to alternate data fields in the resulting chart. Applies only if the PivotGrid contains multiple data fields.
customizeChart	Function	Allows you to customize the Chart's appearance.
customizeSeries	Function	Allows you to customize the series.
dataFieldsDisplayMode	String	Default Value: "splitAxes". Accepts one of the following values: "singleAxis" - Values of all data fields are displayed on a single value axis. "splitAxes" - Each data field gets an individual value axis. Applies only if putDataFieldsInto is "series". "splitPanes" - Each data field gets an individual pane. Applies only if putDataFieldsInto is "series". Applies only if the PivotGrid contains several data fields.
inverted	Boolean	Default Value: false. If true, row field values go to the chart arguments and column field values form series. If false - vice versa.
processCell	Function	Allows you to process cell data before the Chart visualizes it.
putDataFieldsInto	String	Default Value: "series". Accepts one of the following values: "args" - Data fields constitute chart arguments. "series" - Data fields constitute chart series.

Return Value:

Function

| null

Unbinds the Chart. If null, then binding failed.

The customizeChart, customizeSeries, and processCell fields of the integrationOptions object are functions. They accept arguments whose structure is described below.

customizeChart

JavaScript

customizeChart: function (chartOptions) {
    // Change chart properties here
    return chartOptions; // This line is optional
}

The chartOptions object has the following structure:

Field name	Type	Description
valueAxis	Array	Allows you to customize the automatically-created value axes. Each object in this array can contain fields described in the valueAxis property description. When this array holds several objects, use their name field to identify the axis.
panes	Array	Allows you to customize the automatically-created panes. Each object in this array can contain fields described in the panes property description. When this array holds several objects, use their name field to identify the pane.

You can also specify any other Chart properties in this object, except dataSource and seriesTemplate.

customizeSeries

JavaScript

customizeSeries: function (seriesName, seriesOptions) {
    // Change series properties here
    return seriesOptions; // This line is optional
}

The seriesName argument is a string that allows you to identify a series. The seriesOptions argument is an object with the following structure:

Field name	Type	Description
axis	String	The name of the axis to which the series belongs. Has a value only when the chart has multiple axes.
pane	String	The name of the pane the series occupies. Has a value only when the chart has multiple panes.

You can also specify any other series properties in this object.

processCell

JavaScript

processCell: function (cellData) {
    // Process data here
    return cellData; // This line is optional
}

The cellData object has the following structure:

Field name	Type	Description
rowPath	Array	The path to the data cell by row field values.
rowPathFormatted	Array	Same as rowPath, but with format and customizeText applied.
rowFields	Array	Contains objects that are row fields.
maxRowLevel	Number	A zero-based index that indicates the lowest expanded row level. Equals 0 when the pivot grid has no row fields, 1 when all rows are collapsed, 2 when at least one first-level row is expanded, etc.
columnPath	Array	The path to the data cell by column field values.
columnPathFormatted	Array	Same as columnPath, but with format and customizeText applied.
columnFields	Array	Contains objects that are column fields.
maxColumnLevel	Number	A zero-based index that indicates the lowest expanded column level. Equals 0 when the pivot grid has no column fields, 1 when all columns are collapsed, 2 when at least one first-level column is expanded, etc.
dataFields	Array	Contains objects that are data fields.
dataValues	Array	Data of the current cell. Contains more than one value if the pivot grid has multiple data fields.
dataIndex	Number	A zero-based index that indicates which data field and value from the dataFields and dataValues arrays are currently processed.
visible	Boolean	Indicates whether the current cell will be passed to the chart. true if the cell belongs to the deepest expanded level.
chartDataItem	Object	The resulting item passed to the Chart's data source. This object's structure is described in the table below.

The chartDataItem object has the following structure:

Field name	Type	Description
series	String	The name of the series to which the data item belongs.

defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the PivotGrid UI component in an application executed on the desktop.

jQuery

JavaScript

DevExpress.ui.dxPivotGrid.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the PivotGrid properties
    }
});

Angular

TypeScript

import PivotGrid, { Properties } from "devextreme/ui/pivot_grid";
// ...
export class AppComponent {
    constructor () {
        PivotGrid.defaultOptions<Properties>({
            device: { deviceType: "desktop" },
            options: {
                // Here go the PivotGrid properties
            }
        });
    }
}

Vue

<template>
    <div>
        <DxPivotGrid id="pivotGrid1" />
        <DxPivotGrid id="pivotGrid2" />
    </div>
</template>
<script>
import DxPivotGrid from "devextreme-vue/pivot-grid";
import PivotGrid from "devextreme/ui/pivot_grid";

PivotGrid.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the PivotGrid properties
    }
});

export default {
    components: {
        DxPivotGrid
    }
}
</script>

React

import dxPivotGrid from "devextreme/ui/pivot_grid";
import PivotGrid from "devextreme-react/pivot-grid";

dxPivotGrid.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the PivotGrid properties
    }
});

export default function App() {
    return (
        <div>
            <PivotGrid id="pivotGrid1" />
            <PivotGrid id="pivotGrid2" />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the PivotGrid instance.

jQuery

After calling this method, remove the DOM element associated with the UI component:

JavaScript

$("#myPivotGrid").dxPivotGrid("dispose");
$("#myPivotGrid").remove();

Angular

Use conditional rendering instead of this method:

app.component.html

<dx-pivot-grid ...
    *ngIf="condition">
</dx-pivot-grid>

Vue

Use conditional rendering instead of this method:

App.vue

<template>
    <DxPivotGrid ...
        v-if="condition">
    </DxPivotGrid>
</template>

<script>
import DxPivotGrid from 'devextreme-vue/pivot-grid';

export default {
    components: {
        DxPivotGrid
    }
}
</script>

React

Use conditional rendering instead of this method:

App.js

import React from 'react';

import PivotGrid from 'devextreme-react/pivot-grid';

function DxPivotGrid(props) {
    if (!props.shouldRender) {
        return null;
    }

    return (
        <PivotGrid ... >    
        </PivotGrid>
    );
}

class App extends React.Component {
    render() {
        return (
            <DxPivotGrid shouldRender="condition" />
        );
    }
}
export default App;
