Persisting data in server

The modified card data can be persisted in the database using the RESTful web services. All the CRUD operations in the Kanban are done through DataManager. The DataManager has an option to bind all the CRUD related data in server-side.

For your information, the ODataAdaptor persists data in the server as per OData protocol.

In the below section covers how to get the edited data details on the server-side using the UrlAdaptor.

URL adaptor

You can use the UrlAdaptor of DataManager when binding data source for remote data. In the initial load of Kanban, data are fetched from remote data and bound to the Kanban using url property of DataManager.

Using the crudUrl property, the controller action URL can be specified to perform all the CRUD operations at server-side using a single method instead of specifying separate controller action method for CRUD (create, update and delete) operations. The action parameter of crudUrl is used to get the corresponding CRUD action.

The following code example describes the above behavior.

import { Kanban } from '@syncfusion/ej2-kanban';
import { DataManager, UrlAdaptor } from '@syncfusion/ej2-data';

let data: DataManager = new DataManager({
    url: "DataSource",
    crudUrl: "UpdateData",
    adaptor: new UrlAdaptor
});
let kanbanObj: Kanban = new Kanban({
    dataSource: data,
    keyField: 'Status',
    columns: [
        { headerText: 'Backlog', keyField: 'Open' },
        { headerText: 'In Progress', keyField: 'InProgress' },
        { headerText: 'Testing', keyField: 'Testing' },
        { headerText: 'Done', keyField: 'Close' }
    ],
    cardSettings: {
        contentField: 'Summary',
        headerField: 'Id'
    }
});
kanbanObj.appendTo('#Kanban');

The server-side controller code to handle the CRUD operations are as follows.

private NORTHWNDEntities db = new NORTHWNDEntities();
public ActionResult DataSource() {
    var DataSource = db.Tasks.ToList();
    return Json(DataSource, JsonRequestBehavior.AllowGet);
}
public ActionResult UpdateData(EditParams param) {
    if (param.action == "insert" || (param.action == "batch" && param.added != null)) {
        if (param.action == "insert") {
            db.Tasks.Add(param.value);
        } else {
            foreach (var temp in param.added) {
                db.Tasks.Add(temp);
            }
        }
    }
    if (param.action == "update" || (param.action == "batch" && param.changed != null)) {
        if (param.action == "update") {
            Task old = db.Tasks.Where(o => o.Id == param.value.Id).SingleOrDefault();
            if (old != null) {
                db.Entry(old).CurrentValues.SetValues(param.value);
            }
        } else {
            foreach (var temp in param.changed) {
                Task old = db.Tasks.Where(o => o.Id == temp.Id).SingleOrDefault();
                if (old != null) {
                    db.Entry(old).CurrentValues.SetValues(temp);
                }
            }
        }
    }
    if (param.action == "remove" || (param.action == "batch" && param.deleted != null)) {
        if (param.action == "remove") {
            int key = Convert.ToInt32(param.key);
            db.Tasks.Remove(db.Tasks.Where(o => o.Id == key).SingleOrDefault());
        } else {
            foreach (var temp in param.deleted) {
                db.Tasks.Remove(db.Tasks.Where(o => o.Id == temp.Id).SingleOrDefault());
            }
        }
    }
    db.SaveChanges();
    var data = db.Tasks.ToList();
    return Json(data, JsonRequestBehavior.AllowGet);
}

public class EditParams {
    public string key { get; set; }
    public string action { get; set; }
    public List<Tasks> added { get; set; }
    public List<Tasks> changed { get; set; }
    public List<Tasks> deleted { get; set; }
    public Tasks value { get; set; }
}
