DevExtreme Angular - Access the DataSource
Regardless of the data source you use, the TreeList always wraps it in the DataSource. To get a DataSource instance, call the getDataSource() method.
TypeScript
- import { ..., ViewChild } from "@angular/core";
- import { DxTreeListModule, DxTreeListComponent } from "devextreme-angular";
- // ...
- export class AppComponent {
- @ViewChild(DxTreeListComponent) treeList: DxTreeListComponent;
- ds: any = {};
- getDataSource () {
- this.ds = this.treeList.instance.getDataSource();
- }
- }
- @NgModule({
- imports: [
- // ...
- DxTreeListModule
- ],
- // ...
- })
You can now call any method exposed by the DataSource. For example, you can reload data using the reload() method.
JavaScript
- ds.reload();
