Data Binding

28 Jun 201724 minutes to read

Spreadsheet can be populated with external datasource using dataSource property. The dataSource property can be assigned either with the instance of ej.DataManager or JSON data array collection. Spreadsheet supports three different kinds of Data binding.

Local Data
Remote Data
HTML Table Data

Local Data

To bind local data to the Spreadsheet, you can assign a JSON array to the worksheet dataSource property. The following code illustrates how to bind local data to the Spreadsheet,

HTML

<body ng-controller="SpreadsheetCtrl">
     <div id="Spreadsheet" ej-spreadsheet e-sheets="sheetData"></div>
</body>

JAVASCRIPT

var syncApp = angular.module("defaultApp", ["ngRoute", "ejangular"]);
// the datasource "window.filterData" is referred from 'http://js.syncfusion.com/demos/web/scripts/xljsondata.js'
     syncApp.controller('SpreadsheetCtrl', function ($scope,$rootScope) {
         $scope.sheetData = [{
                dataSource: window.filterData,
            }];
     });

The following output is displayed as a result of the above code snippets.

Remote Data

To bind remote data to the Spreadsheet, you can assign a service data as an instance of ej.DataManager to the worksheet dataSource property. The following code illustrates how to bind remote data to the Spreadsheet,

HTML

<body ng-controller="SpreadsheetCtrl">
     <div id="Spreadsheet" ej-spreadsheet e-sheets="sheetData"></div>
</body>

JAVASCRIPT

var syncApp = angular.module("defaultApp", ["ngRoute", "ejangular"]);
     syncApp.controller('SpreadsheetCtrl', function ($scope,$rootScope) {
         $scope.sheetData = [{
                dataSource: ej.DataManager("http://mvc.syncfusion.com/Services/Northwnd.svc/Orders/"),
                query: ej.Query().take(50).select(["OrderID", "CustomerID", "EmployeeID", "ShipName", "ShipAddress"]),
                primaryKey: "OrderID",
            }];
     });

The following output is displayed as a result of the above code snippets.

Offline Mode

To avoid sending post back request to server on every action, Spreadsheet allows user to create, update and delete data on client side. To enable this, set offline property of ej.DataManager as true to fetch all data from server on initial rendering of Spreadsheet and perform all operation on client side.

The following code illustrates offline data binding for Spreadsheet,

HTML

<body ng-controller="SpreadsheetCtrl">
     <div id="Spreadsheet" ej-spreadsheet e-sheets="sheetData"></div>
</body>

JAVASCRIPT

var syncApp = angular.module("defaultApp", ["ngRoute", "ejangular"]);
     syncApp.controller('SpreadsheetCtrl', function ($scope,$rootScope) {
         $scope.sheetData = [{
                dataSource: ej.DataManager({
                url: "http://mvc.syncfusion.com/Services/Northwnd.svc/Orders/",
                offline: true
            }),
            query: ej.Query().select(["OrderID", "CustomerID", "EmployeeID", "ShipName",  "ShipAddress"]),
            primaryKey: "OrderID"
            }];
     });

The following output is displayed as a result of the above code snippets.

HTML Table Data

An HTML Table element can also be used as the data source of Spreadsheet. To use HTML Table as data source, the table element should be passed to worksheet dataSource property of Spreadsheet as an instance of the ej.DataManager. The following code illustrates how to bind HTML Table data to the Spreadsheet,

HTML

<body ng-controller="SpreadsheetCtrl">
     <div id="Spreadsheet" ej-spreadsheet e-sheets="sheetData"></div>

<table id="Table1">
    <thead>
        <tr>
            <th>Laptop</th>
            <th>Model</th>
            <th>Price</th>
            <th>OS</th>
            <th>RAM</th>
            <th>ScreenSize</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Dell Vostro</td>
            <td>2520</td>
            <td>39990</td>
