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

defaultOptions(rule)
defaultOptions is a static method that the widget class supports. The following code demonstrates how to specify default options for all instances of the Slider widget in an application executed on the desktop.
jQuery
DevExpress.ui.dxSlider.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Slider options } });
Angular
import Slider from "devextreme/ui/slider"; // ... export class AppComponent { constructor () { Slider.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Slider options } }); } }
Vue
<template> <div> <DxSlider id="slider1" /> <DxSlider id="slider2" /> </div> </template> <script> import DxSlider from "devextreme-vue/slider"; import Slider from "devextreme/ui/slider"; Slider.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Slider options } }); export default { components: { DxSlider } } </script>
React
import React from "react"; import dxSlider from "devextreme/ui/slider"; import Slider from "devextreme-react/slider"; class App extends React.Component { render () { dxSlider.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Slider options } }) return ( <div> <Slider id="slider1" /> <Slider id="slider2" /> </div> ) } } export default App;
dispose()
After calling this method, remove the DOM element associated with the widget:
$("#mySlider").dxSlider("dispose"); $("#mySlider").remove();
Use this method only if the widget was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-slider ... *ngIf="condition"> </dx-slider>
Vue
<template> <DxSlider ... v-if="condition"> </DxSlider> </template> <script> import DxSlider from 'devextreme-vue/slider'; export default { components: { DxSlider } } </script>
React
import React from 'react'; import Slider from 'devextreme-react/slider'; function DxSlider(props) { if (!props.shouldRender) { return null; } return ( <Slider ... > </Slider> ); } class App extends React.Component { render() { return ( <DxSlider shouldRender="condition" /> ); } } export default App;
