Getting Started

This section explains the steps to create a simple TreeGrid and demonstrates the basic usage of the TreeGrid component using the Essential JS 2 quickstart seed repository. This seed repository is pre-configured with the Essential JS 2 package.

Dependencies

Following is the list of minimum dependencies required to use the treegrid.

|-- @syncfusion/ej2-treegrid
    |-- @syncfusion/ej2-grids
        |-- @syncfusion/ej2-base
        |-- @syncfusion/ej2-data
        |-- @syncfusion/ej2-popups

Setup for local development

Clone the Essential JS 2 quickstart application project from GitHub, and install the necessary npm packages using the following command line scripts.

git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

Configuring system JS

Syncfusion TreeGrid packages should be mapped in the system.config.js configuration file.

System.config({
    paths: {
        'syncfusion:': './node_modules/@syncfusion/',
    },
    map: {
        app: 'app',

        //Syncfusion packages mapping
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
        "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
        "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
        "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
        "@syncfusion/ej2-navigations": "syncfusion:ej2-navigations/dist/ej2-navigations.umd.min.js",
        "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",

        "@syncfusion/ej2-calendars": "syncfusion:ej2-calendars/dist/ej2-calendars.umd.min.js",
        "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
        "@syncfusion/ej2-grids": "syncfusion:ej2-grids/dist/ej2-grids.umd.min.js",
        "@syncfusion/ej2-excel-export": "syncfusion:ej2-excel-export/dist/ej2-excel-export.umd.min.js",
        "@syncfusion/ej2-pdf-export": "syncfusion:ej2-pdf-export/dist/ej2-pdf-export.umd.min.js",

    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');

Adding CSS reference

Combined CSS files are available in the Essential JS 2 package root folder. This can be referenced in your [src/styles/styles.css] using the following code.

@import '../../node_modules/@syncfusion/ej2/material.css';

To know more about individual component CSS, refer to the Individual Component theme files section.

Adding TreeGrid component

You can start adding Essential JS 2 TreeGrid component to the application. To get started, add the TreeGrid component in the app.ts and index.html files using the following code.

Place the following grid code in the app.ts.

import { TreeGrid } from '@syncfusion/ej2-treegrid';

let sampleData: Object[] =  [
    {
        taskID: 1,
        taskName: 'Planning',
        startDate: new Date('02/03/2017'),
        endDate: new Date('02/07/2017'),
        progress: 100,
        duration: 5,
        priority: 'Normal',
        approved: false,
        subtasks: [
            { taskID: 2, taskName: 'Plan timeline', startDate: new Date('02/03/2017'),
                endDate: new Date('02/07/2017'), duration: 5, progress: 100, priority: 'Normal', approved: false },
            { taskID: 3, taskName: 'Plan budget', startDate: new Date('02/03/2017'),
                endDate: new Date('02/07/2017'), duration: 5, progress: 100, priority: 'Low', approved: true },
            { taskID: 4, taskName: 'Allocate resources', startDate: new Date('02/03/2017'),
                endDate: new Date('02/07/2017'), duration: 5, progress: 100, priority: 'Critical', approved: false },
            { taskID: 5, taskName: 'Planning complete', startDate: new Date('02/07/2017'),
                endDate: new Date('02/07/2017'), duration: 0, progress: 0, priority: 'Low', approved: true }
        ]
    },
    {
        taskID: 6,
        taskName: 'Design',
        startDate: new Date('02/10/2017'),
        endDate: new Date('02/14/2017'),
        duration: 3,
        progress: 86,
        priority: 'High',
        approved: false,
        subtasks: [
            { taskID: 7, taskName: 'Software Specification', startDate: new Date('02/10/2017'),
                endDate: new Date('02/12/2017'), duration: 3, progress: 60, priority: 'Normal', approved: false },
            { taskID: 8, taskName: 'Develop prototype', startDate: new Date('02/10/2017'),
                endDate: new Date('02/12/2017'), duration: 3, progress: 100, priority: 'Critical', approved: false },
            { taskID: 9, taskName: 'Get approval from customer', startDate: new Date('02/13/2017'),
                endDate: new Date('02/14/2017'), duration: 2, progress: 100, priority: 'Low', approved: true },
            { taskID: 10, taskName: 'Design Documentation', startDate: new Date('02/13/2017'),
                endDate: new Date('02/14/2017'), duration: 2, progress: 100, priority: 'High', approved: true },
            { taskID: 11, taskName: 'Design complete', startDate: new Date('02/14/2017'),
                endDate: new Date('02/14/2017'), duration: 0, progress: 0, priority: 'Normal', approved: true }
        ]
    }
];

let treeGridObj: TreeGrid = new TreeGrid({
    dataSource: sampleData,
    childMapping: 'subtasks',
    treeColumnIndex: 1,
    columns: [
                { field: 'taskID', headerText: 'Task ID', width: 70, textAlign: 'Right' },
                { field: 'taskName', headerText: 'Task Name', width: 200, textAlign: 'Left' },
                {
                    field: 'startDate', headerText: 'Start Date', width: 90, textAlign: 'Right', type: 'date',format: 'yMd'
                },
                {
                    field: 'endDate', headerText: 'End Date', width: 90, textAlign: 'Right', type: 'date',format: 'yMd'
                },
                { field: 'duration', headerText: 'Duration', width: 80, textAlign: 'Right' },
                { field: 'progress', headerText: 'Progress', width: 80, textAlign: 'Right' },
                { field: 'priority', headerText: 'Priority', width: 90 }
    ],
    height: 380
});

treeGridObj.appendTo('#TreeGrid');

In the above code example, the hierarchical data binding is represented in which the chilMapping property denotes the hierarchy relationship; whereas in self-referencing data binding idMapping and parentIdMapping denotes the hierarchy relationship.

Now, add an HTML div element to act as the treegrid element in index.html using the following code.

Module injection

To create a treegrid with additional features, inject the required modules. The following modules are used to extend grid’s basic functionality.

  • Page: Inject this module to use paging feature.
  • Sort Inject this module to use sorting feature.
  • Filter: Inject this module to use filtering feature.
  • ExcelExport: Inject this module to use Excel export feature.
  • PdfExport: Inject this module to use PDF export feature.

These modules should be injected into the grid using the TreeGrid.Inject method.

Enable paging

The paging feature enables users to view the treegrid record in a paged view. It can be enabled by setting the allowPaging property to true. Inject the Page module as follows. If the Page module is not injected, the pager will not be rendered in the grid. The pager can be customized using the pageSettings property.

In root-level paging mode, paging is based on the root-level rows only i.e., it ignores the child row count and it can be enabled by using the pageSettings.pageSizeMode property.

Enable sorting

The sorting feature enables you to order the records. It can be enabled by setting the allowSorting property to true. Inject the Sort module as follows. If the Sort module is not injected, you cannot sort when a header is clicked. Sorting feature can be customized using the sortSettings property.

Enable filtering

The filtering feature enables you to view the reduced amount of records based on the filter criteria. It can be enabled by setting the allowFiltering property to true. The Filter module has to be injected as follows. If the Filter module is not injected, filter bar will not be rendered in the treegrid. Filtering feature can be customized using the filterSettings property.

By default, filtered records are shown along with its parent records. This behavior can be changed using the filterSettings-hierarchyMode property.
