Access the DataSource

Regardless of the data source you use, the SelectBox always wraps it in a DataSource. Call the getDataSource() method to get the instance of the DataSource.

jQuery
JavaScript
var selectBoxDataSource = $("#selectBoxContainer").dxSelectBox("getDataSource");
Angular
TypeScript
import { DxSelectBoxModule, DxSelectBoxComponent } from 'devextreme-angular';
// ...
export class AppComponent {
    @ViewChild(DxSelectBoxComponent) selectBox: DxSelectBoxComponent;
    let selectBoxDataSource = this.selectBox.instance.getDataSource();
}
@NgModule({
     imports: [
         // ...
         DxSelectBoxModule
     ],
     // ...
 })

Now, you can call any method the DataSource exposes. For example, you can reload data using the load() method.

JavaScript
selectBoxDataSource.load();
