This section helps to understand the getting started of the Ember TreeGrid with the step-by-step instructions.

Getting started TreeGrid with Ember CLI

To quick start with create a new Ember CLI application run the below commands in the command prompt.

> ember new EmberTreeGrid    // Create new Ember CLI app as 'EmberTreeGrid'

> cd EmberTreeGrid

Add syncfusion-ember in package.json to add the Syncfusion Ember add-on into your application EmberTreeGrid.

"devDependencies": {
        ...
	    "syncfusion-ember":"*" //To install the latest version
    }

Disable EXTEND_PROTOTYPES option in the environment.js file under config folder to prevent on function prototype extension in our controls events.

EmberENV: {
        FEATURES: {
            // Here you can enable experimental features on an ember canary build
            // e.g. 'with-controller': true
        },
        EXTEND_PROTOTYPES: false,
    },

Open the command prompt in the root folder and run the command npm install to download the dependent files in node-modules.

Configure Syncfusion source and theme reference

Copy the files ej.web.all.min and jsrender.min into the vendor folder. Import the same into the application using below code in ember-cli-build.js.

module.exports = function(defaults) {
        var app = new EmberApp(defaults, {
            // Add options here
        });
        app.import('vendor/ej.web.all.min.js');
        app.import('vendor/jsrender.min.js');
        return app.toTree();
    };

Create the folder scripts and content in public folder and copy JavaScript and CSS files from /scripts and /content folder which is in JavaScript samples location (Click explore button from the Javascript Dashboard) into created folders. And include the necessary file references in Index page which is in app folder of the Ember application.

HTML

<head>    
        <link rel="stylesheet" href="content/ejthemes/default-theme/ej.web.all.min.css">
    </head>
    <body>        
    </body>

Configure the routes for the Router

Use the below commands in the command prompt for generate routing to create template default.hbs file in templates folder and router default.js file in routes folder. It also add the routing content in router.js.

JAVASCRIPT

> ember generate route treegrid/default    // Defining routes

Create TreeGrid sample in Ember CLI Application

Use below code in default.hbs in templates folder to render the TreeGrid.

HTML

{{ej-treegrid id="TreeGridDefault" 
                e-dataSource=model.dataSource 
                e-childMapping="subtasks"
                e-treeColumnIndex= 1
                e-isResponsive=true                
                e-columns=model.columns            
                }}

Use the below code in default.js in routes folder to bind the model to the TreeGrid.

import Route from '@ember/routing/route';
let sampleData = [
    {
        taskID: 1,
        taskName: "Planning",
        startDate: new Date("02/03/2014"),
        endDate: new Date("02/07/2014"),
        progress: 100,
        duration: 5,
        priority: "Normal",
        approved: false,
        subtasks: [
            { taskID: 2, taskName: "Plan timeline", startDate: new Date("02/03/2014"), endDate: new Date("02/07/2014"), duration: 5, progress: 100, priority: "Normal", approved: false },
            { taskID: 3, taskName: "Plan budget", startDate: new Date("02/03/2014"), endDate: new Date("02/07/2014"), duration: 5, progress: 100, approved: true },
            { taskID: 4, taskName: "Allocate resources", startDate: new Date("02/03/2014"), endDate: new Date("02/07/2014"), duration: 5, progress: 100, priority: "Critical", approved: false },
            { taskID: 5, taskName: "Planning complete", startDate: new Date("02/07/2014"), endDate: new Date("02/07/2014"), duration: 0, progress: 0, priority: "Low", approved: true }
        ]
    },
    {
        taskID: 6,
        taskName: "Design",
        startDate: new Date("02/10/2014"),
        endDate: new Date("02/14/2014"),
        duration: 3,
        progress: 86,
        priority: "High",
        approved: false,
        subtasks: [
            { taskID: 7, taskName: "Software Specification", startDate: new Date("02/10/2014"), endDate: new Date("02/12/2014"), duration: 3, progress: 60, priority: "Normal", approved: false },
            { taskID: 8, taskName: "Develop prototype", startDate: new Date("02/10/2014"), endDate: new Date("02/12/2014"), duration: 3, progress: 100, priority: "Critical", approved: false },

            { taskID: 10, taskName: "Design Documentation", startDate: new Date("02/13/2014"), endDate: new Date("02/14/2014"), duration: 2, progress: 100, approved: true }           
        ]
    }
];
export default Route.extend({
    model() {
        return {
            dataSource: sampleData,
            columns: [
