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 protocol the TreeList uses; 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.

You should configure remoteOperations to notify the TreeList that the server handles data.

jQuery
JavaScript
$(function() {
    var serviceUrl = "http://url/to/my/service";
    $("#treeListContainer").dxTreeList({
        dataSource: DevExpress.data.AspNet.createStore({
            key: "ID",
            loadUrl: serviceUrl + "/GetAction",
            insertUrl: serviceUrl + "/InsertAction",
            updateUrl: serviceUrl + "/UpdateAction",
            deleteUrl: serviceUrl + "/DeleteAction"
        }),
        remoteOperations: { 
            filtering: true,
            sorting: true,
            grouping: true
        },
        // ...
    })
});

import { DxTreeListModule } from "devextreme-angular";

    store: CustomStore;
    constructor() {
        let serviceUrl = "http://url/to/my/service";
        this.store = createStore({
            key: "ID",
            loadUrl: serviceUrl + "/GetAction",
            insertUrl: serviceUrl + "/InsertAction",
            updateUrl: serviceUrl + "/UpdateAction",
            deleteUrl: serviceUrl + "/DeleteAction"
        })
    }
}
@NgModule({
    imports: [

    ],
