DevExtreme Angular - Web API Service
DevExtreme provides the DevExtreme.AspNet.Data extension to access an ASP.NET Web API service. This extension consists of two parts: the server-side part implements data processing on the server according to the DevExtreme widgets' protocol; the client-side part creates and configures a CustomStore to access the server from the client. The following code shows how to use the extension's client-side createStore method:
TypeScript
HTML
- import { DxSankeyModule } from "devextreme-angular";
- import CustomStore from "devextreme/data/custom_store";
- import { createStore } from "devextreme-aspnet-data-nojquery";
- // ...
- export class AppComponent {
- store: CustomStore;
- constructor() {
- const serviceUrl: string = "http://url/to/my/service";
- this.store = createStore({
- key: ["from", "to"],
- loadUrl: serviceUrl + "/GetAction"
- })
- }
- }
- @NgModule({
- imports: [
- // ...
- DxSankeyModule
- ],
- // ...
- })
- <dx-sankey
- [dataSource]="store"
- sourceField="from"
- targetField="to"
- weightField="amount">
- </dx-sankey>
