Each data source or remote service uses different way in accepting request and sending back the
response. DataManager
cannot anticipate every way a data source
works. To tackle this problem the DataManager
uses the adaptor concept to communicate with particular data source.
For local data sources, the role of the data adaptor is to query the JavaScript object array
based on the Query
object and manipulate them.
When comes with remote datasource, the data adaptor is used to send the request that the server can understand and process the server response.
The adaptor can be assigned using the adaptor property of the
DataManager
.
JsonAdaptor is used to query and manipulate JavaScript object array.

UrlAdaptor act as the base adaptor for interacting with remote data services. Most of the built-in adaptors are derived from the UrlAdaptor.
import { DataManager, Query, UrlAdaptor } from '@syncfusion/ej2-data';
const SERVICE_URI = 'http://controller.com/actions';
new DataManager({
url: SERVICE_URI,
adaptor: new UrlAdaptor()
}).executeQuery(new Query().take(8)).then((e) => {
//e.result will contain the records
});
UrlAdaptor expects response as a JSON object with properties result and count which contains the collection of entities and the total number of records respectively.
The sample response object should be as follows,
{
"result": [{..}, {..}, {..}, ...],
"count": 67
}
OData
is standardized protocol for
creating and consuming data. You can retrieve data from OData service using
DataManager
. The ODataAdaptor helps you to interact with OData service. You can
refer to the following code example of remote Data binding using OData service.

import { DataManager, Query, ODataAdaptor, ReturnOption } from '@syncfusion/ej2-data';

By default, ODataAdaptor is used by
DataManager
.
The ODataV4 is an improved version of OData protocols and the
DataManager
can also retrieve and consume OData v4 services. For more details on
OData v4 Services, refer the
odata documentation
.
You can use the ODataV4Adaptor to interact with ODataV4 service.

You can use the WepApiAdaptor to interact with Web API created with OData endpoint. The WepApiAdaptor is extended from the ODataAdaptor. Hence to use WepApiAdaptor, the endpoint should understand the OData formatted queries send along with request.
To enable OData query option for Web API, please refer to the documentation
import { DataManager, Query, WebApiAdaptor } from '@syncfusion/ej2-data';
const SERVICE_URI = 'http://controller.com/api';
new DataManager({
url: SERVICE_URI,
adaptor: new WebApiAdaptor()
}).executeQuery(new Query().take(8)).then((e) => {
//e.result will contain the records
});
WepApiAdaptor expects JSON response from the server and the response object should contain properties Items and Count whose values are collection of entities and total count of the entities respectively.
The sample response object should look like below.
{
Items: [{..}, {..}, {..}, ...],
Count: 830
}
The WebMethodAdaptor is used to bind data source from remote services and code behind methods. It can be enabled in Grid using Adaptor property of DataManager as WebMethodAdaptor.
For every operations, an AJAX post will be send to the specified data service.
import { DataManager, Query, WebMethodAdaptor } from '@syncfusion/ej2-data';
let SERVICE_URI = 'Default.aspx/DataSource';
new DataManager({
url: SERVICE_URI,
adaptor: new WebMethodAdaptor
}).executeQuery(new Query().take(8)).then((e) => {
//e.result will contain the records
});
WebMethodAdaptor expects JSON response from the server and the response object should contain properties result and count whose values are collection of entities and total count of the entities respectively.
The sample response object should look like below.
{
result: [{..}, {..}, {..}, ...],
count: 830
}
The controller method’s data parameter name must be value.
Sometimes the built-in adaptors does not meet your requirement. In such cases you can create your own adaptor.
To create and use custom adaptor, please refer to the below steps.
DataManager
.For the sake of demonstrating custom adaptor approach, we are going to see how to add serial number for the records by overriding the built-in response processing using processResponse method of the ODataAdaptor.
import { Component, OnInit } from '@angular/core';
import { DataManager, Query, ODataAdaptor, ReturnOption } from '@syncfusion/ej2-data';
const SERVICE_URI: string = 'https://js.syncfusion.com/demos/ejServices/Wcf/Northwind.svc/Orders';
class SerialNoAdaptor extends ODataAdaptor {
public processResponse(): object {
let i: number = 0;
//calling base class processResponse function
let original: object[] = super.processResponse.apply(this, arguments);
//Adding serial number
original.forEach((item: object) => item['Sno'] = ++i);
return original;
}
}
