How to implement inline editing in the Angular Pivot Table?

First, we need to create the Angular Pivot Table component by following the instructions provided in the getting started guide.

Built-in option

The built-in inline editing feature lets you modify a cell’s value directly without an edit dialog. This feature is only available when the cell’s value originates from a single raw data. It applies to all editing modes, including normal, batch, dialog, and column commands. You can activate inline editing by setting the allowInlineEditing property in the editSettings to true. 

app.component.html

<div style="margin-top: 100px;">
  <ejs-pivotview #pivotview id='PivotView' [dataSourceSettings]=dataSourceSettings showFieldList='true' [showTooltip]='false' width='100%' height='500'
  [gridSettings]='gridSettings' [editSettings]='editSettings'></ejs-pivotview>
</div>

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import {
  IDataOptions,
  IDataSet,
  PivotViewModule,
  FieldListService,
  PivotView,
  CellEditSettings,
} from '@syncfusion/ej2-angular-pivotview';
import { GridSettings } from '@syncfusion/ej2-pivotview/src/pivotview/model/gridsettings';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [RouterOutlet, PivotViewModule],
  templateUrl: './app.component.html',
  styleUrl: './app.component.css',
  providers: [FieldListService],
})

export class AppComponent implements OnInit {
  public dataSourceSettings: IDataOptions | undefined;
  public gridSettings: GridSettings | undefined;
  public editSettings?: CellEditSettings;

  @ViewChild('pivotview')
  public pivotObj: PivotView | undefined;

  getPivotData(): IDataSet[] {
    let pivotData: IDataSet[] = [
      {
        Amount: 2100,
        Country: 'Canada',
        Date: 'FY 2005',
        Product: 'Bike',
        Quantity: 22,
        State: 'Alberta',
      }
    ];

    return pivotData;
  }

  ngOnInit(): void {
    this.gridSettings = {
      columnWidth: 160,
    } as GridSettings;
    this.editSettings = {
      allowEditing: true,
      allowInlineEditing: true,
    } as CellEditSettings;
    this.dataSourceSettings = {
      values: [
        { name: 'Sold', caption: 'Units Sold' },
        { name: 'Amount', caption: 'Sold Amount' },
      ],
      formatSettings: [{ name: 'Amount', format: 'C' }],
      columns: [
        { name: 'Year' },
        { name: 'Order_Source', caption: 'Order Source' },
      ],
      dataSource: this.getPivotData(),
      rows: [{ name: 'Country' }, { name: 'Products' }],
      filters: [],
      expandAll: false,
      enableSorting: true,
    };
  }
}

Refer to the following GIF image.

Convert the built-in editing dialog into an inline editing option

If the cell’s value is derived from more than one raw data source, an editing popup opens, allowing you to edit the raw data for a specific cell. However, we can restrict the editing dialog using the drillThrough event if you wish to edit these cells like inline editing.

The values in the Pivot Table can then be changed and updated using inline editing when double-clicking the value cells for the combinational data source. It allows you to modify both the specified Pivot Table cell value and the underlying data information at the sample level.

Refer to the following code example. 

app.component.html

<div style="margin-top: 100px;">
  <ejs-pivotview #pivotview [dataSourceSettings]=dataSourceSettings showFieldList='true' [showTooltip]='false' width='100%' height='500'
  allowDrillThrough='true' [gridSettings]='gridSettings' (drillThrough)="drillThrough($event)"></ejs-pivotview>
</div>

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import { IDataOptions, IDataSet, PivotViewModule, FieldListService, PivotView } from '@syncfusion/ej2-angular-pivotview';
import { GridSettings } from '@syncfusion/ej2-pivotview/src/pivotview/model/gridsettings';
import { NumericTextBox } from '@syncfusion/ej2-inputs';

@Component({

  public indexObject: any;
  public eventArgs: any;
  public actualText: string | undefined;
  public updatedData: any;

  getPivotData(): IDataSet[] {
    let pivotData: IDataSet[] = [
      { 'Sold': 31, 'Amount': 52824, 'Country': 'France', 'Products': 'Mountain Bikes', 'Year': 'FY 2015', 'Quarter': 'Q1' },
      { 'Sold': 51, 'Amount': 86904, 'Country': 'France', 'Products': 'Mountain Bikes', 'Year': 'FY 2015', 'Quarter': 'Q2' },
      { 'Sold': 90, 'Amount': 153360, 'Country': 'France', 'Products': 'Mountain Bikes', 'Year': 'FY 2015', 'Quarter': 'Q3' },
      { 'Sold': 25, 'Amount': 42600, 'Country': 'France', 'Products': 'Mountain Bikes', 'Year': 'FY 2015', 'Quarter': 'Q4' }];

    return pivotData;

  drillThrough(args: any) {
    args.cancel = true;
    this.eventArgs = args;
    this.eventArgs.currentTarget.children[0].style.display = 'none';

    if (!document.body.querySelector('#' + this.pivotObj?.element.id + 'inline')) {
      let div = document.createElement('input');
      div.id = this.pivotObj?.element.id + 'inline';
      args.currentTarget.appendChild(div);
      let numeric: NumericTextBox = new NumericTextBox({
        value: args.currentCell.value,
        change: this.onChange.bind(this),
        blur: this.onBlur.bind(this),
      });
      numeric.appendTo(div);
      this.eventArgs.currentCell.value = this.updatedData;
      numeric.focusIn();
    }
  }

  onChange(args: any) {
    let differenceOfValue: number;
    let splitRawData: number;
    if (args.previousValue < args.value) {
      differenceOfValue = args.value - args.previousValue;
    }
    else {
      differenceOfValue = args.previousValue - args.value;
    }
    splitRawData = differenceOfValue / this.eventArgs.rawData.length;
    for (let i: number = 0; i < this.eventArgs.rawData.length; i++) {
      if (args.previousValue < args.value) {
        this.eventArgs.rawData[i][this.actualText as string] =
          this.eventArgs.rawData[i][this.actualText as string] + splitRawData;
      } else {
        this.eventArgs.rawData[i][this.actualText as string] =
          this.eventArgs.rawData[i][this.actualText as string] - splitRawData;
      }
    }
  }

  onBlur(args: any) {
    for (let k: number = 0; k < this.indexObject.length; k++) {
      if (this.pivotObj) {
        this.pivotObj.engineModule.data[this.indexObject[k]] = this.eventArgs.rawData[k];
      }
    }
    this.pivotObj?.setProperties(
      { dataSourceSettings: { dataSource: this.pivotObj?.engineModule.data } },
      true
    );
    this.pivotObj?.engineModule.updateGridData(this.pivotObj?.dataSourceSettings);
    if (this.pivotObj) {
      this.pivotObj.pivotValues = this.pivotObj?.engineModule.pivotValues;
    }
    this.updatedData = args.value;
  }

  ngOnInit(): void {
    this.gridSettings = {
      columnWidth: 160
    } as GridSettings;
    this.dataSourceSettings = {
      values: [
        { name: 'Sold', caption: 'Units Sold' },
        { name: 'Amount', caption: 'Sold Amount' },
      ],
      formatSettings: [{ name: 'Amount', format: 'C' }],
      columns: [
        { name: 'Year' },
        { name: 'Order_Source', caption: 'Order Source' },
      ],
      dataSource: this.getPivotData(),
      rows: [{ name: 'Country' }, { name: 'Products' }],
      filters: [],
      expandAll: false,
      enableSorting: true
    };
  }
}

That’s it. Double-click any value cell in the Angular Pivot Table to update the values using inline editing instead of the editing dialog.

After customization:

How does the above customization work?

When we double-click a value cell in the Angular Pivot Table, the drillThrough event is triggered before the editing popup is displayed. That event allows us to restrict the editing popup. To modify and update the cell value, we need to insert an input element in it. In the above code example, we have added the Syncfusion Angular Numeric Textbox component in the value cell. 

Then, we used the Angular Numeric TextBox’s change and blur events to modify and update the data source. In the change event, the raw data for that Pivot value is updated in response to the changed data. If the modified data exceeds the previous value, the difference is divided and added evenly to all the underlying raw data. If the modified data is less than the previous value, the difference is divided and subtracted equally from all the underlying raw data. The blur event refreshes the Angular Pivot Table with the modified data source.
