Show field list when pivot table empty in React Pivotview component

30 Jan 20233 minutes to read

When there are no fields in a pivot table’s row, column, value, and filter axes, a field list can still be displayed. To do so, use the dataBound event and call the onShowFieldList method as shown below.

index.jsx

import { FieldList, Inject, PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { pivotData } from './datasource';
function App() {
    let dataSourceSettings = {
        dataSource: pivotData,
    };
    let pivotObj;
    return (<PivotViewComponent ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings} dataBound={dataBound.bind(this)} showFieldList={true}><Inject services={[FieldList]}/></PivotViewComponent>);
    function dataBound() {
        if (pivotObj && pivotObj.dataSourceSettings.values.length === 0) {
            pivotObj.pivotFieldListModule.dialogRenderer.onShowFieldList();
        }
    }
}
;
export default App;
ReactDOM.render(<App />, document.getElementById('sample'));

index.tsx

import { FieldList, IDataOptions, IDataSet, Inject, PivotViewComponent } from '@syncfusion/ej2-react-pivotview';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { pivotData } from './datasource';

function App() {

  let dataSourceSettings: IDataOptions = {
    dataSource: pivotData as IDataSet[],
  }
  let pivotObj: PivotViewComponent;
  
  return (<PivotViewComponent  ref={d => pivotObj = d} id='PivotView' height={350} dataSourceSettings={dataSourceSettings} dataBound={dataBound.bind(this)} showFieldList={true}><Inject services={[FieldList]} /></PivotViewComponent>);

  function dataBound(): void {
    if (pivotObj && pivotObj.dataSourceSettings.values.length === 0) {
      (pivotObj.pivotFieldListModule.dialogRenderer as any).onShowFieldList();
    }
  }
};

export default App;
ReactDOM.render(<App />, document.getElementById('sample'));
