Multiple gantt exporting in EJ2 TypeScript Gantt control

2 May 202324 minutes to read

PDF export provides an option for exporting multiple Gantt to same file. In this exported document, each Gantt will be exported to a new page of the document in same file.

import { Gantt, Toolbar,PdfExport, Selection } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';

Gantt.Inject(Toolbar, PdfExport, Selection);

let firstGantt: Gantt = new Gantt({
    dataSource: [GanttData[0]],
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    treeColumnIndex: 1,
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    projectStartDate: new Date('03/31/2019'),
    projectEndDate: new Date('04/14/2019'),
    height: '280px',
});
firstGantt.appendTo('#GanttExport1');

let secondGantt: Gantt = new Gantt({
    dataSource: [GanttData[1]],  
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    treeColumnIndex: 1,
    toolbar: ['PdfExport'],
    height: '250px'
});
secondGantt.appendTo('#GanttExport2');

firstGantt.toolbarClick = (args: Object) => {
    if (args.item.id === 'GanttExport1_pdfexport') {
        let firstGanttPdfExport: Promise<Object> = gantt.pdfExport({}, true);
        firstGanttPdfExport.then(function(pdfData){
            secondGantt.pdfExport({}, false, pdfData);
        });
    }
}

To customize PDF export

PDF export provides an option to customize the mapping of Gantt to exported PDF document.

File name for exported document

You can assign a file name for the exported document by defining the fileName property in pdfExportProperties.

import { Gantt, Toolbar, PdfExport, Selection, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
           fileName:"new.pdf"
        };
        gantt.pdfExport(exportProperties);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler
});
gantt.appendTo('#GanttExport');

How to change page orientation

Page orientation can be changed to Portrait (Default Landscape) for the exported document using the property pdfExportProperties.pageOrientation.

import { Gantt, Toolbar, PdfExport, Selection, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
           pageOrientation: 'Portrait'
        };
        gantt.pdfExport(exportProperties);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler
});
gantt.appendTo('#GanttExport');

Export current view data

PDF export provides an option to export the current view data into PDF. To export current view data alone, define the exportType to CurrentViewData.

import { Gantt, Toolbar, PdfExport, Selection, Filter, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection, Filter);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
             exportType: 'CurrentViewData'
        };
        gantt.pdfExport(exportProperties);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    allowFiltering: true,
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler
});
gantt.appendTo('#GanttExport');

By default, we render the default footer for a PDF file, this can be enabled or disabled by using the enableFooter property.

import { Gantt, Toolbar, PdfExport, Selection, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
            enableFooter: false
        };
        gantt.pdfExport(exportProperties);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',

Export hidden columns

PDF export provides an option to export hidden columns of Gantt by defining the includeHiddenColumn to true.

import { Gantt, Toolbar, PdfExport, Selection, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
            includeHiddenColumn: true
        };
        gantt.pdfExport(exportProperties);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        child: 'subtasks'
    },
    columns: [
        { field: 'TaskID'},
        { field: 'TaskName', visible: false},
        { field: 'StartDate'},
        { field: 'Duration'},
        { field: 'Progress'}
    ],
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler
});
gantt.appendTo('#GanttExport');

Export predecessor lines

By using showPredecessorLines, you can hide or show predecessor lines in the exported PDF document.

import { Gantt, Toolbar, PdfExport, Selection, PdfExportProperties } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let exportProperties: PdfExportProperties = {
            showPredecessorLines: true
        };
        gantt.pdfExport();
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        dependency: 'Predecessor',
        child: 'subtasks'
    },
    columns: [
        { field: 'TaskID'},
        { field: 'TaskName', visible: false},
        { field: 'StartDate'},
        { field: 'Duration'},
        { field: 'Progress'}
    ],
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler
});
gantt.appendTo('#GanttExport');

Show or hide columns on exported PDF

You can show a hidden column or hide a visible column while exporting the Gantt using the toolbarClick and beforePdfExport events.

You can show or hide columns by setting the column.visible property to true or false respectively.

In the following example, there is a hidden column Duration in the Gantt. While exporting, we have changed Duration to visible column and StartDate to hidden column.

import { Gantt, Toolbar, PdfExport, Selection } from '@syncfusion/ej2-gantt';
import { EJ2Instance } from '@syncfusion/ej2-navigations';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';
import { GanttData } from 'datasource.ts';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        let obj: any = (<EJ2Instance>document.getElementById('GanttExport')).ej2_instances[0]
        obj.treeGrid.columns[2].visible = false;
        gantt.pdfExport();
    }
};

let beforePdfExport: EmitType<Object> = (args: Object) => {
    let obj: any = (<EJ2Instance>document.getElementById('GanttExport')).ej2_instances[0]
    obj.treeGrid.columns[3].visible = true;
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
        id: 'TaskID',
        name: 'TaskName',
        startDate: 'StartDate',
        duration: 'Duration',
        progress: 'Progress',
        dependency: 'Predecessor',
        child: 'subtasks'
    },
    columns: [
        { field: 'TaskID'},
        { field: 'TaskName'},
        { field: 'StartDate'},
        { field: 'Duration', visible: false},
        { field: 'Progress'}
    ],
    allowPdfExport: true,
    toolbar: ['PdfExport'],
    toolbarClick: clickHandler,
    beforePdfExport: beforePdfExport
});
gantt.appendTo('#GanttExport');

Conditional cell formatting

TreeGrid cells in the exported PDF can be customized or formatted using the pdfQueryCellInfo event. In this event, you can format the treegrid cells of exported PDF document based on the column cell value.

In the following sample, the background color is set for Progress column in the exported document by using the args.style and backgroundColor properties.

import { Gantt, Toolbar, PdfExport, Selection, PdfQueryTimelineCellInfoEventArgs } from '@syncfusion/ej2-gantt';
import { GanttData } from 'datasource.ts';
import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        gantt.pdfExport();
    }
};

let pdfQueryCellInfo: EmitType<PdfQueryCellInfoEventArgs> = (args: PdfQueryCellInfoEventArgs) => {

import { ClickEventArgs } from '@syncfusion/ej2-navigations/src/toolbar/toolbar';
import { PdfColor } from '@syncfusion/ej2-pdf-export';
import { GanttData } from 'datasource.ts';

Gantt.Inject(Toolbar, PdfExport, Selection);

let clickHandler: EmitType<ClickEventArgs> = (args: ClickEventArgs) => {
    if (args.item.id === 'GanttExport_pdfexport') {
        gantt.pdfExport();
    }
};

let pdfQueryTimelineCellInfo: EmitType<PdfQueryTimelineCellInfoEventArgs> = (args: PdfQueryTimelineCellInfoEventArgs) => {
    args.timelineCell.backgroundColor= new PdfColor(240, 248, 255);
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {

    if (args.item.id === 'GanttExport_pdfexport') {
        gantt.pdfExport();
    }
};

let pdfQueryTaskbarInfo: EmitType<Object> = (args: Object) => {
    if(args.data.Progress < 50 && !args.data.hasChildRecords) {
        args.taskbar.progressColor = new PdfColor(205, 92, 92);
        args.taskbar.taskColor =  args.taskbar.taskBorderColor = new PdfColor(240, 128, 128);
    }
};

let gantt: Gantt = new Gantt({
    dataSource: GanttData,
    height: '450px',
    taskFields: {
