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:

jQuery
JavaScript
$(function() {
    var serviceUrl = "http://url/to/my/service";
    $("#sankeyContainer").dxSankey({
        dataSource: DevExpress.data.AspNet.createStore({
            key: ["from", "to"],
            loadUrl: serviceUrl + "/GetAction"
        }),
        sourceField: "from",
        targetField: "to",
        weightField: "amount"
    })
});
Angular
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>
