Introduction

In this article, we will learn about TreeGrid control by using jQWidgets Framework with AngularJS. I hope you will like this.

What’s jQWidgets Framework?

jQWidgets represents a framework based on jQuery for building web-based applications that run on PC, Touch, and mobile devices. jQWidgets includes more than 60 UI widgets. jQWidgets is not a modified version of the jQuery UI toolkit. All widgets are designed from the ground-up and based on a powerful common core. The framework core provides fundamental capabilities like support for widget extensions and inheritance, widget settings, internal event handling and routing, property change notifications, device and browser compatibility detection and adjustments.
You can download zip file from here jQWidgets.

Create your Application

Open Visual Studio and select File >> New Project.

The "New Project" window will pop up. Select ASP.NET Web Application (.NET Framework), name your project, and click OK.

Next, new window will pop up for selecting the template. Choose Empty and click OK.

Angular Part

Here, we need to create new folder which includes two JavaScript files respectively, GridApp.js and GridController.js.

In order to create new JS files, right click on GridApp folder > Add > JavaScript File.

GridApp.js

var app = angular.module('myApp', ['ngRoute', 'jqwidgets']);
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/TreeGrid', {
templateUrl: '/GridApp/Views/TreeGridDemo.html',
controller: 'GridController'
}).otherwise({
controller: 'GridController'
});
}]);
Here, we have defined AngularJS module (in our case myApp), and injecting ngRoute module which allow us to use routing then jqwidgets module for using TreeGrid control.
GridController.js
app.controller('GridController', function ($scope) {
//json data
$scope.employees = [
{
"EmployeeID": 2, "FirstName": "Andrew", "LastName": "Fuller", "Country": "USA", "Title": "Vice President, Sales", "HireDate": "1992-08-14 00:00:00", "BirthDate": "1952-02-19 00:00:00", "City": "Tacoma", "Address": "908 W. Capital Way", "expanded": "true",

}
]
}];
//create TreeGrid
$scope.treeGridSettings =
{
width: 900,
source: new $.jqx.dataAdapter({
dataType: "json",
dataFields: [
{ name: 'EmployeeID', type: 'number' },
{ name: 'FirstName', type: 'string' },

hierarchy:
{

},
id: 'EmployeeID',
localData: $scope.employees
}),
sortable: true,
columns: [
{ text: 'FirstName', dataField: 'FirstName', width: 200 },
{ text: 'LastName', dataField: 'LastName', width: 120 },

{ text: 'Country', dataField: 'Country' }
]
};
})

Create HTML Page

For doing this, right click on Views folder > Add > HTML Page.

TreeGridDemo.html

<!DOCTYPE html>
<html>
<head>
<title>.: TreeGrid Demo :.</title>
<meta charset="utf-8" />
</head>
<body>
<h2>Tree Grid with AngularJS</h2>
<div>
<jqx-tree-grid jqx-settings="treeGridSettings"></jqx-tree-grid>
</div>
</body>
</html>

Before running, we need to add some libraries inside index.html, as shown below.
