Complex data binding in EJ2 JavaScript Grid control

13 Apr 20234 minutes to read

You can achieve complex data binding in the grid by using the dot(.) operator in the column.field.

index.js
index.html
var grid = new ej.grids.Grid({
    dataSource: complexData,
    columns: [
        { field: 'EmployeeID', headerText: 'Employee ID', textAlign: 'Right', width: 100 },
        { field: 'Name.FirstName', headerText: 'First Name', width: 120 },
        { field: 'Name.LastName', headerText: 'Last Name', width: 100 },
        { field: 'Title', headerText: 'Title', width: 150 }
    ],
    height: 315
});
grid.appendTo('#Grid');

For OData and ODataV4 adaptors, you need to add expand query to the query property (of Grid), to eager load the complex data.

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

 let  data: DataManager = new DataManager({
       adaptor: new ODataAdaptor(),
       crossDomain: true,
       url: 'https://js.syncfusion.com/demos/ejServices/Wcf/Northwind.svc/Orders'
     });
 let query: Query = new Query().expand('Employee');

 let grid: Grid = new Grid({
    dataSource: data,
    query: query,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'ShipCity', headerText: 'Ship City', width: 100 },
        { field: 'Employee.City', headerText: 'Employee City', width: 150 }
    ],
    height: 315
});
grid.appendTo('#Grid');
