Angular Common - Utils - pdfExporter

An object that serves as a namespace for the methods that export DevExtreme UI components to PDF.

exportDataGrid(options) CTP

Exports grid data to a PDF file.

import { exportDataGrid } from "devextreme/pdf_exporter"

Parameters:

options:

PdfExportDataGridProps

Export settings.

Return Value:

Promise<void> (jQuery or native)

A Promise that is resolved when the grid data is prepared for export. It is a native Promise or a jQuery.Promise when you use jQuery.

NOTE

This functionality is available as a community technology preview (CTP). Should you have any questions or suggestions prior to its official release, please create a new ticket in the DevExpress Support Center.

This method requires the jsPDF library to export data and the jsPDF-AutoTable plugin to create tables in exported files.

You can call this method at any point in your application. In this example, we call this method in a standalone button's onClick handler:

jQuery

JavaScript

HTML

$(function(){
    $('#exportButton').dxButton({
        // ...
        onClick: function() {
            const doc = new jsPDF();
            DevExpress.pdfExporter.exportDataGrid({
                jsPDFDocument: doc,
                component: dataGrid
            }).then(function() {
                doc.save('Customers.pdf');
            });
        }
    });

    const dataGrid = $('#gridContainer').dxDataGrid({
        // ...
    }).dxDataGrid('instance');
});

View Demo

This method requires the jsPDF library to export data and the jsPDF-AutoTable plugin to create tables in exported files.

The exportGantt(options) method allows you to save information about the Gantt chart's layout, appearance, and tasks. This method supports the following options:

createDocumentMethod - Specifies a function that creates a PDF document.
format {string | width?: number, height?: number } - Specifies the document size.
landscape {boolean} - Specifies whether to use horizontal orientation for the document.
fileName {string} - Specifies the file name.
exportMode {"all", "treeList", "chart"} - Specifies the part of the component to export (chart area, tree list area, or the entire component).
dateRange {"all" | "visible" | startDate? : Date, endDate? : Date, startIndex? : number, endIndex? : number } - Restricts data output against a specified date range.
margins { left?: number, top?: number, right?: number, bottom?: number } - Specifies the outer indents of the exported area.

The exporter supports standard PDF fonts. Refer to the Use of Unicode Characters / UTF-8 article to get information on how to use custom fonts for exporting.

You can call the exportGantt method at any point in your application. In the example below, this method is called in a standalone toolbar item's onClick event handler:

JavaScript

const ganttInstance = $('#gantt').dxGantt({
    toolbar: {
        items: [
            // ...

                    icon: 'exportpdf',
                    hint: 'Export to PDF',

The following code snippet illustrates how to process the PDF document when the export is complete:

JavaScript

var gantt = $("#ganttContainer").dxGantt("instance");
gantt.exportToPdf({
    format: "A4",
    landscape: true,
    exportMode: "chart",
    dateRange: "visible"
}).then(function(doc) { 
    doc.addPage(); 
    // your code
    doc.save('customDoc.pdf'); 
});

To print the exported PDF document, call the autoPrint method:

JavaScript

var gantt = $("#ganttContainer").dxGantt("instance");
gantt.exportToPdf({
    format: "A4",
    landscape: true,
    exportMode: "chart",
    dateRange: "visible"
}).then(function(doc) { 
    doc.autoPrint(); 
    window.open(doc.output('your_url'), '_blank');
});
