Data Binding

The Grid uses DataManager, which supports both RESTful JSON data services binding and local JavaScript object array binding. The dataSource property can be assigned either with the instance of DataManager or JavaScript object array collection. It supports two kinds of data binding method:

Local data
Remote data

Local Data

To bind local data to the grid, you can assign a JavaScript object array to the dataSource property. The local data source can also be provided as an instance of the DataManager.

By default, DataManager uses JsonAdaptor for local data-binding.

Remote data

To bind remote data to grid component, assign service data as an instance of DataManager to the dataSource property. To interact with remote data source, provide the endpoint url.

By default, DataManager uses ODataAdaptor for remote data-binding.

Binding with OData services

OData is a standardized protocol for creating and consuming data. You can retrieve data from OData service using the DataManager. Refer to the following code example for remote Data binding using OData service.

Binding with OData v4 services

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 to the odata documentation. To bind OData v4 service, use the ODataV4Adaptor.

Web API

You can use WebApiAdaptor to bind grid with Web API created using OData endpoint.

var data = new ej.data.DataManager({
    url: '/api/OrderAPI',
    adaptor: new ej.data.WebApiAdaptor()
});

var grid = new ej.grids.Grid({
    dataSource: data,
    columns: [
                { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120, type: 'number' },
                { field: 'CustomerID', width: 140, headerText: 'Customer ID', type: 'string' },
                { field: 'Freight', headerText: 'Freight', textAlign: 'Right', width: 120, format: 'C' },
                { field: 'OrderDate', headerText: 'Order Date', width: 140, format: 'yMd' }
    ]
});

grid.appendTo('#Grid');

The response object should contain properties, Items and Count, whose values are a collection of entities and total count of the entities, respectively.

The sample response object should look like this:

{
    Items: [{..}, {..}, {..}, ...],
    Count: 830
}

Remote Save Adaptor

You may need to perform all Grid Actions in client-side except the CRUD operations, that should be interacted with server-side to persist data. It can be achieved in Grid by using RemoteSaveAdaptor.

Datasource must be set to json property and set RemoteSaveAdaptor to the adaptor property. CRUD operations can be mapped to server-side using updateUrl, insertUrl, removeUrl, batchUrl, crudUrl properties.

You can use the following code example to use RemoteSaveAdaptor in Grid.

ej.grids.Grid.Inject(ej.grids.Edit, ej.grids.Toolbar);

var dataSource = new ej.data.DataManager({
    json: data,
    adaptor: new ej.data.RemoteSaveAdaptor(),
    insertUrl: '/Home/Insert',
    updateUrl: '/Home/Update',
    removeUrl: '/Home/Delete'
});

var grid = new ej.grids.Grid({
    dataSource: dataSource,
    toolbar: ['Add', 'Edit', 'Delete', 'Update', 'Cancel'],
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true },
    columns: [
                { field: 'OrderID', headerText: 'Order ID', isPrimaryKey: true, textAlign: 'Right', width: 120, type: 'number' },
                { field: 'CustomerID', width: 140, headerText: 'Customer ID', type: 'string' },
                { field: 'Freight', headerText: 'Freight', textAlign: 'Right', width: 120, format: 'C' },
                { field: 'OrderDate', headerText: 'Order Date', width: 140, format: 'yMd' }
    ]
});

grid.appendTo('#Grid');

The following code example describes the CRUD operations handled at server-side.

    public ActionResult Update(OrdersDetails value)
    {
        ...
        return Json(value);
    }
    public ActionResult Insert(OrdersDetails value)
    {
        ...
       return Json(value);
    }
    public ActionResult Delete(int key)
    {
        ...
        return Json(data);
    }

Custom adaptor

You can create your own adaptor by extending the built-in adaptors. The following demonstrates custom adaptor approach and how to add a serial number for the records by overriding the built-in response processing using the processResponse method of the ODataAdaptor.

    processResponse() {

        // calling base class processResponse function
        var original = super.processResponse.apply(this, arguments);
        // adding serial number
        original.result.forEach(function(item){item['Sno'] = ++i});
        return { result: original.result, count: original.count };
    }
}

var data = new ej.data.DataManager({
    url: 'https://services.odata.org/V4/Northwind/Northwind.svc/Orders/?$top=7',
    adaptor: new SerialNoAdaptor()
});

var grid = new ej.grids.Grid({
    dataSource: data,
    columns: [
        { field: 'Sno', width: 120, headerText: 'SNO', textAlign: 'Right' },
        { field: 'CustomerID', width: 140, headerText: 'Customer Name', type: 'string' },
        { field: 'Freight', headerText: 'Freight', textAlign: 'Right', width: 120, format: 'C2' },
        { field: 'OrderDate', headerText: 'Order Date', width: 140, format: 'yMd' }
    ]
});

Offline mode

On remote data binding, all grid actions such as paging, sorting, editing, grouping, filtering, etc, will be processed on server-side. To avoid postback for every action, set the grid to load all data on initialization and make the actions process in client-side. To enable this behavior, use the offline property of DataManager.

Sending additional parameters to the server

To add a custom parameter to the data request, use the addParams method of Query class. Assign the Query object with additional parameters to the grid query property.

The parameters added using the query property will be sent along with the data request for every grid action.

Handling HTTP error

During server interaction from the grid, some server-side exceptions may occur, and you can acquire those error messages or exception details in client-side using the actionFailure event.

The argument passed to the actionFailure event contains the error details returned from the server.

The actionFailure event will be triggered not only for the server errors, but also when there is an exception while processing the grid actions.

Binding with ajax

You can use Grid dataSource property to bind the datasource to Grid from external ajax request. In the below code we have fetched the datasource from the server with the help of ajax request and provided that to dataSource property by using onSuccess event of the ajax.

ej.grids.Grid.Inject(ej.grids.Page);

let grid = new ej.grids.Grid({
    allowPaging: true,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
        { field: 'CustomerID', headerText: 'Customer ID', textAlign: 'Right', width: 120 },
        { field: 'EmployeeID', headerText: 'Employee ID', textAlign: 'Right', width: 120 },
        { field: 'ShipCountry', headerText: 'Ship Country', textAlign: 'Right', width: 120 }
    ]
});
grid.appendTo('#Grid');

let button = document.getElementById('btn');
button.addEventListener("click", function(e){
    let ajax = new ej.base.Ajax("https://ej2services.syncfusion.com/production/web-services/api/Orders", "GET");
    ajax.send();
    ajax.onSuccess = function (data) {
        grid.dataSource = JSON.parse(data);
    };
});

If you bind the dataSource from this way, then it acts like a local dataSource. So you cannot perform any server side crud actions.
