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.

defaultOptions(rule)
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 Popup UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxPopup.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Popup options } });
Angular
import Popup from "devextreme/ui/popup"; // ... export class AppComponent { constructor () { Popup.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Popup options } }); } }
Vue
<template> <div> <DxPopup id="popup1" /> <DxPopup id="popup2" /> </div> </template> <script> import DxPopup from "devextreme-vue/popup"; import Popup from "devextreme/ui/popup"; Popup.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Popup options } }); export default { components: { DxPopup } } </script>
React
import React from "react"; import dxPopup from "devextreme/ui/popup"; import Popup from "devextreme-react/popup"; class App extends React.Component { render () { dxPopup.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Popup options } }) return ( <div> <Popup id="popup1" /> <Popup id="popup2" /> </div> ) } } export default App;
dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myPopup").dxPopup("dispose"); $("#myPopup").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-popup ... *ngIf="condition"> </dx-popup>
Vue
<template> <DxPopup ... v-if="condition"> </DxPopup> </template> <script> import DxPopup from 'devextreme-vue/popup'; export default { components: { DxPopup } } </script>
React
import React from 'react'; import Popup from 'devextreme-react/popup'; function DxPopup(props) { if (!props.shouldRender) { return null; } return ( <Popup ... > </Popup> ); } class App extends React.Component { render() { return ( <DxPopup shouldRender="condition" /> ); } } export default App;
