Localization in JavaScript ComboBox control

08 May 2023 / 2 minutes to read

The Localization library allows you to localize static text content of the noRecordsTemplate and actionFailureTemplate  properties according to the culture currently assigned to the ComboBox.

Locale key en-US (default)
noRecordsTemplate No records found
actionFailureTemplate The request failed

Loading translations

To load translation object to your application, use load function of L10n class.

In the following sample, French culture is set to the ComboBox and no data is loaded. Hence, the noRecordsTemplate property displays its text in French culture initially, and if the sample is run offline, the actionFailureTemplate property displays its text appropriately.

import { ComboBox } from '@syncfusion/ej2-dropdowns';
// import L10n class for load function
import { L10n, setCulture} from '@syncfusion/ej2-base';
import { DataManager, ODataV4Adaptor, Query } from '@syncfusion/ej2-data';
// bind remotedata to showcase actionFailureTemplate in offline.
let customerData: DataManager = new DataManager({
    url: '',
    adaptor: new ODataV4Adaptor,
    crossDomain: true

let ComboBoxObj: ComboBox = new ComboBox({
    dataSource: customerData,
    // set locale culture to ComboBox
    locale: 'fr-BE',
    // map appropriate column
    fields: { text: 'ContactName', value: 'CustomerID' },
    // take 0 item to showcase noRecordsTemplate property.
    query: new Query().select(['ContactName', 'CustomerID']).take(0);
    // set placeholder to ComboBox input element
    placeholder: 'Sélectionnez un client'

    'fr-BE': {
       'dropdowns': {
             'noRecordsTemplate': "Aucun enregistrement trouvé",
             'actionFailureTemplate': "Modèle d'échec d'action"
