Data binding in EJ2 TypeScript Spreadsheet control

2 May 202324 minutes to read

The Spreadsheet uses DataManager, which supports both RESTful JSON data services and local JavaScript object array binding to a range. The dataSource property can be assigned either with the instance of DataManager or JavaScript object array collection.

To bind data to a cell, use cell data binding support.

Local data

To bind local data to the Spreadsheet, you can assign a JavaScript object array to the dataSource property.

Refer to the following code example for local data binding.

import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';
import { data } from './datasource.ts';

//Initialize the SpreadSheet control
let spreadsheet: Spreadsheet = new Spreadsheet({
  sheets: [{
                ranges: [{ dataSource: data }],
                columns: [{ width: 80 }, { width: 80 },{ width: 80},
                          { width: 160 }, { width: 100 }, {width: 150}]
            }],
  }
});
spreadsheet.appendTo('#spreadsheet');

The local data source can also be provided as an instance of the DataManager. By default, DataManager uses JsonAdaptor for local data-binding.

Remote data

To bind remote data to the Spreadsheet control, assign service data as an instance of DataManager to the dataSource property. To interact with remote data source, provide the service endpoint url.

Refer to the following code example for remote data binding.

import { DataManager, ODataAdaptor } from '@syncfusion/ej2-data';
import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

class CustomAdaptor extends ODataAdaptor {
    public processResponse(): Object {
        let result: Object[] = [];
        let original: { result: Object[], count: number } = super.processResponse.apply(this, arguments);
        original.result.forEach((item: { SNo: number }, idx: number) => {
            result[idx] = {};
            Object.keys(item).forEach((key: string) => {
                if (['OrderID', 'CustomerID', 'ShipName', 'ShipCity', 'ShipCountry'].indexOf(key) > -1) {
                    result[idx][key] = item[key];
                }
            });
        });
        return { result: result, count: original.count };
    }
}
//Initialize DataManager.
let data: DataManager = new DataManager({
    //Remote service url.
    url: 'https://services.syncfusion.com/js/production/api/Orders',
    adaptor: new CustomAdaptor,
    crossDomain: true
});

let spreadsheet: Spreadsheet = new Spreadsheet({
    sheets: [
        {
            rows: [{
                cells: [{ value: 'Order ID' }, { value: 'Customer Name' }, { value: 'Ship Name' },
                { value: 'Ship City' }, { value: 'Ship Country' }]
            }],
            ranges: [{ dataSource: data, showFieldAsHeader: false, startCell: 'A2' }],
            columns: [
                { width: 80 }, { width: 100 }, { width: 82 },
                { width: 160 }, { width: 110 }, { width: 130 }
            ]
        }]
});

spreadsheet.appendTo('#spreadsheet');

By default, DataManager uses ODataAdaptor for remote data-binding.

Binding with OData services

OData is a standardized protocol for creating and consuming data. You can retrieve data from OData service using the DataManager. Refer to the following code example for remote Data binding using OData service.

import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';
import { DataManager, ODataAdaptor } from '@syncfusion/ej2-data';

//Initialize DataManager.
let data: DataManager = new DataManager({
  url: 'https://services.syncfusion.com/js/production/api/Orders',
  adaptor: new ODataAdaptor(),
  crossDomain: true
});

let spreadsheet: Spreadsheet = new Spreadsheet({
  sheets: [
    {
      name: 'Order details',
      ranges: [{ dataSource: data }],
      columns: [
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 280 },
        { width: 180 },
        { width: 80 },
        { width: 180 },
        { width: 180 },
      ]
    }
  ],
  created: (): void => {
    //Applies cell and number formatting to specified range of the active sheet.
    spreadsheet.cellFormat({ fontWeight: 'bold', textAlign: 'center', verticalAlign: 'middle' },
      'A1:K1');
  }
});

spreadsheet.appendTo('#spreadsheet');

Web API

You can use WebApiAdaptor to bind spreadsheet with Web API created using OData endpoint.

import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';
import { DataManager, WebApiAdaptor } from '@syncfusion/ej2-data';

//Initialize DataManager.
let data: DataManager = new DataManager({
  url: 'https://services.syncfusion.com/js/production/api/Orders',
  crossDomain: true,
  adaptor: new WebApiAdaptor()
});

let spreadsheet: Spreadsheet = new Spreadsheet({
  sheets: [
    {
      name: 'Order details',
      ranges: [{ dataSource: data }],
      columns: [
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 80 },
        { width: 280 },
        { width: 180 },
        { width: 80 },
        { width: 180 },
        { width: 180 },
      ]
    }
  ],
  created: (): void => {
    //Applies cell and number formatting to specified range of the active sheet.
    spreadsheet.cellFormat({ fontWeight: 'bold', textAlign: 'center', verticalAlign: 'middle' },
      'A1:K1');
  }
});

spreadsheet.appendTo('#spreadsheet');

Cell data binding

The Spreadsheet control can bind the data to individual cell in a sheet . To achive this you can use the
value property.

Refer to the following code example for cell data binding.

import { Spreadsheet } from '@syncfusion/ej2-spreadsheet';

//Initialize the SpreadSheet control
let spreadsheet: Spreadsheet = new Spreadsheet({
    sheets: [
        {
            name: 'Monthly Budget',
            selectedRange: 'D13',
            rows: [
                {
                    cells: [
                        { value: 'Category', style: { fontWeight: 'bold', textAlign: 'center' } },
                        { value: 'Planned cost', style: { fontWeight: 'bold', textAlign: 'center' } },
                        { value: 'Actual cost', style: { fontWeight: 'bold', textAlign: 'center' } },
                        { value: 'Difference', style: { fontWeight: 'bold', textAlign: 'center' } }
                    ]
                },
                {
                    cells: [
                        { value: 'Food' },
                        { value: '$7000' },
                        { value: '$8120' },
                        { formula: '=B2-C2', format: '$#,##0.00' }
                    ]
                },
                {
                    cells: [
                        { value: 'Loan' },
                        { value: '$1500' },
                        { value: '$1500' },
                        { formula: '=B3-C3', format: '$#,##0.00' }
                    ]
                },
                {
                    cells: [
                        { value: 'Medical' },
                        { value: '$300' },
                        { value: '$0' },
                        { formula: '=B4-C4', format: '$#,##0.00' }
                    ]
                },
                {
                    index: 5,
                    cells: [
                        { index: 2, value: 'Total Difference:', style: { fontWeight: 'bold', textAlign: 'right' } },
                        { formula: '=D2+D4', format: '$#,##0.00', style: { fontWeight: 'bold' } }
                    ]
                }
            ],
            columns: [
                { width: 110 }, { width: 115 }, { width: 110 }, { width: 100 }
            ]
        }
    ]
});

The cell data binding also supports formula, style, number format, and more.

Dynamic data binding and Datasource change event

You can dynamically change the datasource of the spreadsheet by changing the dataSource property of the range object of the sheet. The dataSourceChanged event handler will be triggered when editing, inserting, and deleting a row in the datasource range. This event will be triggered with a parameter named action which indicates the edit, add and delete actions for the respective ones.

The following table defines the arguments of the dataSourceChanged event.

Property Type Description
action string Indicates the type of action such as edit, add, and delete performed in the datasource range.
data object[] Modified data for edit action; New data for add action; Deleted data for delete action.
rangeIndex number Specifies the range index of the datasource.
sheetIndex number Specifies the sheet index of the datasource.

For add action, the value for all the fields will be null in the data. In the case that you do not want the primary key field to be null which needs to be updated in the backend service, you can use edit action after updating the primary key field to update in the backend service.


For inserting a row at the end of the datasource range, you should insert a row below at the end of the range to trigger the dataSourceChanged event with action add.

import { Spreadsheet, DataSourceChangedEventArgs } from '@syncfusion/ej2-spreadsheet';
import { data, itemData } from './datasource.ts';

let spreadsheet: Spreadsheet = new Spreadsheet({
        showRibbon: false,
        showFormulaBar: false,
        sheets: [
            {
                ranges: [{ dataSource: data }],
                columns: [
                    { width: 90 }, { width: 100 }, { width: 96 },
                    { width: 120 }, { width: 130 }, { width: 120 }
                ]
            }],
        dataSourceChanged: (args: DataSourceChangedEventArgs) => {
            appendElement("Data source changed with" + "<b>&nbsp;" + args.action + "</b> action<hr>");
        }
});

spreadsheet.appendTo('#spreadsheet');

document.getElementById('changeDataBtn').addEventListener('click', ()=> {
    spreadsheet.sheets[0].ranges[0].dataSource = itemData;
});

document.getElementById('clearBtn').addEventListener('click', ()=> {
    document.getElementById('EventLog').innerHTML = "";
});

function appendElement(html: string): void {
     let span: HTMLElement = document.createElement("span");
     span.innerHTML = html;
     let log: HTMLElement = document.getElementById('EventLog');
     log.insertBefore(span, log.firstChild);
}
