Custom Fields

You can change the default fields of dialog using fields property inside the dialogSettings property. The key property used to map the dataSource value and rendered the corresponding component based on specified type property.

The following types are available in dialog fields.

  • String
  • Numeric
  • TextArea
  • DropDown
  • TextBox
  • Input

If type is not defined in the fields, then it renders as the HTML input element in dialog.

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.

You can map the CRUD operation in Kanban can be mapped to server-side controller actions using the properties insertUrl, removeUrl, updateUrl, and crudUrl.

  • insertUrl – You can perform single insertion operation on server-side.
  • updateUrl – You can update single data on server-side.
  • removeUrl – You can remove single data on server-side.
  • crudUrl – You can perform bulk data operation on server-side.

The following code example describes the above behavior.

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

let data: DataManager = new DataManager({
url: 'Home/DataSource',
updateUrl: 'Home/Update',
insertUrl: 'Home/Insert',
removeUrl: 'Home/Delete',
adaptor: new UrlAdaptor(),
crossDomain: true
});
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.

Copied to clipboard
private NORTHWNDEntities db = new NORTHWNDEntities();
public ActionResult DataSource() {
var DataSource = db.Tasks.ToList();
return Json(DataSource, JsonRequestBehavior.AllowGet);
}
public ActionResult Insert(Params value) {
//Insert card data into the database
return Json(value, JsonRequestBehavior.AllowGet);
}
public ActionResult Update(Params value) {
//Update card data into the database
return Json(value, JsonRequestBehavior.AllowGet);
}
public void Delete(Params value) {
//Delete card data from the database
}

public class Params {
public int Id { get; set; }
public string Status { get; set; }
public string Summary { get; set; }
public string Assignee { get; set; }
}

Insert card

Using the insertUrl property, you can specify the controller action mapping URL to perform insert operation on the server-side.

The following code example describes the above behavior.

Copied to clipboard
public ActionResult Insert(Params value)
{
//Insert card in the database
}

The newly added record details are bound to the value parameter.

Update card

Using the updateUrl property, the controller action mapping URL can be specified to perform save/update operation on the server-side.

The following code example describes the above behavior.

Copied to clipboard
public ActionResult Update(Params value)
{
//Update card data in the database
}

The updated record details are bound to the value parameter.

Delete card

Using the removeUrl property, the controller action mapping URL can be specified to perform delete operation on the server-side.

The following code example describes the above behavior.

Copied to clipboard
public void Delete(int key)
{
//Delete card in the database
}

The deleted card primary key value is bound to the key parameter.

CRUD URL

Using the crudUrl property, the controller action mapping URL can be specified to perform all the CRUD operations at the server-side using a single method instead of specifying a separate controller action method for CRUD (insert, 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.

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

let data: DataManager = new DataManager({
url: 'Home/DataSource',
updateUrl: 'Home/UpdateData',
insertUrl: 'Home/UpdateData',
removeUrl: 'Home/UpdateData',
crudUrl: 'Home/UpdateData',
adaptor: new UrlAdaptor(),
crossDomain: true
});
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');
Copied to clipboard
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();
return Json(param, 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; }
}

The crudUrl is used to update the bulk data sent to the server-side. Multiple selections and sortBy as Index properties are used for crudUrl properties to update the modified bulk data to the server-side.
