beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myGantt").dxGantt("dispose"); $("#myGantt").remove();
Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-gantt ... *ngIf="condition"> </dx-gantt>
Vue
<template> <DxGantt ... v-if="condition"> </DxGantt> </template> <script> import DxGantt from 'devextreme-vue/gantt'; export default { components: { DxGantt } } </script>

exportToPdf(options) CTP
A Promise that is resolved after the Gantt chart is exported. It is a native Promise or a jQuery.Promise when you use jQuery.
The exportToPdf method allows you to save information about the Gantt chart's layout, appearance, and tasks. This method supports the following options:
- 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 which 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 } - Specifies the date range for which to export tasks.
- margins { left?: number, top?: number, right?: number, bottom?: number } - Specifies the outer indents of the exported area.
Note that you should link the jspdf.js and jspdf-autotable.js libraries to your project.
Use the following settings to export the Gantt chart to a PDF document:
var gantt = $("#ganttContainer").dxGantt("instance"); gantt.exportToPdf({ format: "A4", landscape: true, exportMode: "chart", dateRange: "visible" });
Use the following settings to process the PDF document when the export is complete:
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'); });
Use the following settings to print the exported PDF document:
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'); });

scrollToDate(date)
You can pass the date to the scrollToDate method in the following formats:
-
var gantt = $("#ganttContainer").dxGantt("instance"); gantt.scrollToDate(new Date("December 17, 2020"));
Number - Specifies a date as a timestamp (total milliseconds since 1970/01/01).
var gantt = $("#ganttContainer").dxGantt("instance"); gantt.scrollToDate(1876800000000);
String - Specifies a date as a string value.
var gantt = $("#ganttContainer").dxGantt("instance"); gantt.scrollToDate("2020/01/01");
Note that the scrollToDate method scrolls to a date inside the current scroll area. You can zoom the chart to resize the viewport.
