Pdf export in Angular Gantt component

PDF export allows exporting Gantt data to PDF document. You need to use the pdfExport method for exporting. To enable PDF export in the Gantt, set the allowPdfExport to true.

To export data to PDF document, inject the PdfExport module in Gantt.

Note: Currently, we do not have support for exporting manually scheduled tasks.

app.component.ts

import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';

import { GanttComponent, ToolbarItem, SelectionSettingsModel } from '@syncfusion/ej2-angular-gantt';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';
import { editingData } from './data';

@Component({
    selector: 'app-root',
    template:
       `<ejs-gantt #gantt id="ganttDefault" height="430px" [dataSource]="data" [taskFields]="taskSettings" [toolbar]="toolbar"
       (toolbarClick)="toolbarClick($event)" allowPdfExport='true'></ejs-gantt>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;
    public toolbar?: ToolbarItem[];
    @ViewChild('gantt', {static: true})
    public ganttChart?: GanttComponent;
    public ngOnInit(): void {
        this.data = editingData;
        this.taskSettings = {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            duration: 'Duration',
            progress: 'Progress',
            child: 'subtasks'
        };
        this.toolbar =  ['PdfExport'];
    }
    public toolbarClick(args: ClickEventArgs): void {
            if (args.item.id === 'ganttDefault_pdfexport') {
                this.ganttChart!.pdfExport();

    };
}

Indicators in PDF exporting

The PDF export functionality allows users to export Gantt charts enriched with dynamic indicators and accompanying images.
These indicators, represented by images,can be effortlessly defined using the base64 encoding value in the data object of datasource.This data object field should be mapped to indiactor property of task fields.

app.component.ts

import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';

       (toolbarClick)="toolbarClick($event)" allowPdfExport='true'></ejs-gantt>`,
    encapsulation: ViewEncapsulation.None
})
export class AppComponent{
    // Data for Gantt
    public data?: object[];
    public taskSettings?: object;
    public toolbar?: ToolbarItem[];
    @ViewChild('gantt', {static: true})
    public ganttChart?: GanttComponent;
    public ngOnInit(): void {
        this.data = editingData;
        this.taskSettings = {
            id: 'TaskID',
            name: 'TaskName',
            startDate: 'StartDate',
            duration: 'Duration',
            progress: 'Progress',
            child: 'subtasks'
        };
        this.toolbar =  ['PdfExport'];
    }
    public toolbarClick(args: ClickEventArgs): void {
            if (args.item.id === 'ganttDefault_pdfexport') {
                this.ganttChart!.pdfExport();

Exporting Gantt data as a blob object

In Gantt, you can export the Gantt chart data as a blob object, which allows you to preview or modify the data before exporting it.

To export the Gantt chart data as a blob object, follow these steps:

step 1: pdfExport fourth argument set as true.

step 2: Then , pdfExpComplete return as blob object.

app.component.ts

import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';

import { Gantt, Toolbar, PdfExport, Selection,  ExcelExportService, PdfExportService,
   ToolbarService, ToolbarItem, GanttComponent } from '@syncfusion/ej2-angular-gantt';

    }
    public toolbarClick(args: ClickEventArgs): void {
            if (args.item.id === 'ganttDefault_pdfexport') {
                this.ganttChart!.pdfExport(undefined,undefined,undefined,true);
            }

            // In this `then` function, we can get blob data through the arguments after promise resolved.
            this.exportBlob(e.blobData);
        });
    }

    pdfExpComplete(args: PdfExportCompleteArgs) {
        // This event will be triggered when pdf exporting.
        args.promise!.then((e: { blobData: Blob }) => {
            // In this `then` function, we can get blob data through the arguments after promise resolved.
            this.exportBlob(e.blobData);

Single page exporting in gantt

In Gantt, we have provided support to export the Gantt component where each rows are auto-fit to the PDF document page width by setting isFitToWidth as true in fitToWidthSettings of PdfExportProperties.

Also, we can customize the chart width and grid width in exported file using chartWidth and gridWidth by defining it as percentage in string.

Exporting with templates

Exporting with column template

The PDF export functionality allows to export Grid columns that include images, hyperlinks, and custom text to an PDF document using pdfQueryCellInfo event.

In the following sample, the hyperlinks and images are exported to PDF using hyperlink and image properties in the pdfQueryCellInfo event.

Note: PDF Export supports base64 string to export the images.

app.component.ts

  GanttComponent,
  ToolbarItem,
  PdfExportProperties,

Exporting with taskbar template

The PDF export functionality allows to export taskbar templates that include images and text to an PDF document using pdfQueryTaskbarInfo event. Taskbars in the exported PDF document can be customized or formatted using the pdfQueryTaskbarInfo event for parent taskbar templates, taskbar templates and milestone templates.

In the following sample, taskbar templates with images and text are exported to PDF using taskbarTemplate properties in the pdfQueryTaskbarInfo event.

Note: PDF Export supports base64 string to export the images.
