Configuring system JS

Syncfusion Gantt packages have to be mapped in the system.config.js configuration file.

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

        //Syncfusion packages mapping

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.

Copied to clipboard
@import '../../node_modules/@syncfusion/ej2/material.css';

Adding Gantt component

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

Place the following gantt code in the app.ts.

Copied to clipboard
import { Gantt } from '@syncfusion/ej2-gantt';

let gantt: Gantt = new Gantt({
    dataSource: [
        {
            TaskID: 1,
            TaskName: 'Project Initiation',
            StartDate: new Date('04/02/2019'),
            EndDate: new Date('04/21/2019'),
            subtasks: [
                { TaskID: 2, TaskName: 'Identify Site location', StartDate: new Date('04/02/2019'), Duration: 0, Progress: 50 },
                { TaskID: 3, TaskName: 'Perform Soil test', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50, resources: [2, 3, 5]  },
                { TaskID: 4, TaskName: 'Soil test approval', StartDate: new Date('04/02/2019'), Duration: 4,Predecessor:"2FS", Progress: 50 },
            ]
        },
        {
            TaskID: 5,
            TaskName: 'Project Estimation',
            StartDate: new Date('04/02/2019'),
            EndDate: new Date('04/21/2019'),
            subtasks: [
                { TaskID: 6, TaskName: 'Develop floor plan for estimation', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50, resources: [4] },
                { TaskID: 7, TaskName: 'List materials', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50, resources: [4, 8], },
                { TaskID: 8, TaskName: 'Estimation approval', StartDate: new Date('04/04/2019'), Duration: 0,Predecessor:"6SS", Progress: 50, resources: [12, 5] }
            ]
        },
    ],
    height: '450px',
    taskFields: {
                id: 'TaskID',
                name: 'TaskName',
                startDate: 'StartDate',
                endDate: 'EndDate',
                progress: 'Progress',
                dependency: 'Predecessor',
                child: 'subtasks'
        }
    });

 gantt.appendTo('#Gantt');

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

                { TaskID: 7, TaskName: 'List materials', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 },
                { TaskID: 8, TaskName: 'Estimation approval', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 }
            ]
        },
    ];

    let gantt: Gantt = new Gantt({
         dataSource: data,
     });

gantt.appendTo('#Gantt');

Mapping task fields

The data source fields that are required to render the tasks are mapped to the Gantt control using the taskFields property.

Copied to clipboard
import { Gantt} from '@syncfusion/ej2-gantt';

let gantt: Gantt = new Gantt({
         dataSource: data,
         height:'450px',
         taskFields: {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            duration: 'Duration',
            dependency: 'Predecessor',
            progress: 'Progress',
            child: 'subtasks',
        },
  });

gantt.appendTo('#Gantt');

Defining columns

Gantt has an option to define columns as an array. You can customize the Gantt columns using the following properties:

  • field: Maps the data source fields to the columns.
  • headerText: Changes the title of columns.
  • textAlign: Changes the alignment of columns. By default, columns will be left aligned. To change the columns to right align, set textAlign to right.
  • format: Formats the number and date values to standard or custom formats. Here, it is defined for the conversion of numeric values to currency.
Copied to clipboard
import { Gantt } from '@syncfusion/ej2-gantt';
import { data } from 'datasource.ts';

let gantt: Gantt = new Gantt({
dataSource: data,
columns: [
        { field: 'TaskID', headerText: 'Task ID', textAlign: 'Right', width: '250' },
        { field: 'TaskName', headerText: 'Task Name', width: '250' },
        { field: 'StartDate', headerText: 'Start Date', width: '250' },
        { field: 'Duration', headerText: 'Duration', width: '250' },
        { field: 'Progress', headerText: 'Progress', width: '250', format: 'C' },
    ],
});
gantt.appendTo('#Gantt');

Module injection

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

  • Edit: Inject this module to use the editing feature.
  • Filter: Inject this module to use the filtering feature.
  • Sort: Inject this module to use the sorting feature.

These modules should be injected into the Gantt using the Gantt.Inject method.

Enable editing

The editing feature enables you to edit the tasks in the Gantt control. It can be enabled by using the editSettings.allowEditing and editSettings.allowTaskbarEditing properties.

The following editing options are available to update the tasks in Gantt:

  • Cell
  • Dialog
  • Taskbar
  • Connector line

Cell editing

Modify the task details through cell editing by setting the edit mode to Auto. Inject the Edit module as follows. If the Edit module is not injected, you cannot edit the cell when a grid cell is clicked.

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 the records when a header is clicked. The sorting feature can be customized using the sortSettings property.

Enabling predecessors or task relationships

Predecessor or task dependency in the Gantt control is used to depict the relationship between the tasks.

  • Start to Start (SS): You cannot start a task until the dependent task starts.
  • Start to Finish (SF): You cannot finish a task until the dependent task finishes.
  • Finish to Start (FS): You cannot start a task until the dependent task completes.
  • Finish to Finish (FF): You cannot finish a task until the dependent task completes. You can show the relationship in tasks by using the dependency property as shown in the following code example.
