beginUpdate()
Postpones rendering that can negatively affect performance until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.

defaultOptions(rule)
Name | Type | Description |
---|---|---|
device | | |
Device parameters. |
options |
Options to be applied. |
defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Gantt UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxGantt.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Gantt properties } });
Angular
import Gantt, { Properties } from "devextreme/ui/gantt"; // ... export class AppComponent { constructor () { Gantt.defaultOptions<Properties>({ device: { deviceType: "desktop" }, options: { // Here go the Gantt properties } }); } }
Vue
<template> <div> <DxGantt id="gantt1" /> <DxGantt id="gantt2" /> </div> </template> <script> import DxGantt from "devextreme-vue/gantt"; import Gantt from "devextreme/ui/gantt"; Gantt.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Gantt properties } }); export default { components: { DxGantt } } </script>
React
import dxGantt from "devextreme/ui/gantt"; import Gantt from "devextreme-react/gantt"; dxGantt.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Gantt properties } }); export default function App() { return ( <div> <Gantt id="gantt1" /> <Gantt id="gantt2" /> </div> ) }
You can also set rules for multiple device types:
jQuery
const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { DevExpress.ui.dxGantt.defaultOptions({ device: deviceConfig, options: { // Here go the Gantt properties } }); });
Angular
import Gantt, { Properties } from "devextreme/ui/gantt"; // ... export class AppComponent { constructor () { const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { Gantt.defaultOptions<Properties>({ device: deviceConfig, options: { // Here go the Gantt properties } }); }); } }
Vue
<template> <div> <DxGantt /> </div> </template> <script> import DxGantt from "devextreme-vue/gantt"; import Gantt from "devextreme/ui/gantt"; const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { Gantt.defaultOptions({ device: deviceConfig, options: { // Here go the Gantt properties } }); }); export default { components: { DxGantt } } </script>

dispose()
jQuery
After calling this method, remove the DOM element associated with the UI component:
$("#myGantt").dxGantt("dispose"); $("#myGantt").remove();
Angular
Use conditional rendering instead of this method:
<dx-gantt ... *ngIf="condition"> </dx-gantt>
Vue
Use conditional rendering instead of this method:
<template> <DxGantt ... v-if="condition"> </DxGantt> </template> <script> import DxGantt from 'devextreme-vue/gantt'; export default { components: { DxGantt } } </script>
React
Use conditional rendering instead of this method:
import React from 'react'; import Gantt from 'devextreme-react/gantt'; function DxGantt(props) { if (!props.shouldRender) { return null; } return ( <Gantt ... > </Gantt> ); } class App extends React.Component { render() { return ( <DxGantt shouldRender="condition" /> ); } } export default App;
endUpdate()
Refreshes the UI component after a call of the beginUpdate() method.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the Gantt instance found in an element with the myGantt
ID:
// Modular approach import Gantt from "devextreme/ui/gantt"; ... let element = document.getElementById("myGantt"); let instance = Gantt.getInstance(element) as Gantt; // Non-modular approach let element = document.getElementById("myGantt"); let instance = DevExpress.ui.dxGantt.getInstance(element);

scrollToDate(date)
You can pass the date to the scrollToDate method in the following formats:
-
JavaScript
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).
JavaScriptvar gantt = $("#ganttContainer").dxGantt("instance"); gantt.scrollToDate(1876800000000);
String - Specifies a date as a string value.
JavaScriptvar 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.
