beginUpdate()

defaultOptions(rule)
Specifies the device-dependent default configuration options for this component.
The component's default device options.
defaultOptions is a static method that the widget class supports. The following code demonstrates how to specify default options for all instances of the ActionSheet widget in an application executed on the desktop.
jQuery
DevExpress.ui.dxActionSheet.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the ActionSheet options } });
Angular
import ActionSheet from "devextreme/ui/action_sheet"; // ... export class AppComponent { constructor () { ActionSheet.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the ActionSheet options } }); } }
Vue
<template> <div> <DxActionSheet id="actionSheet1" /> <DxActionSheet id="actionSheet2" /> </div> </template> <script> import DxActionSheet from "devextreme-vue/action-sheet"; import ActionSheet from "devextreme/ui/action_sheet"; ActionSheet.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the ActionSheet options } }); export default { components: { DxActionSheet } } </script>
React
import React from "react"; import dxActionSheet from "devextreme/ui/action_sheet"; import ActionSheet from "devextreme-react/action-sheet"; class App extends React.Component { render () { dxActionSheet.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the ActionSheet options } }) return ( <div> <ActionSheet id="actionSheet1" /> <ActionSheet id="actionSheet2" /> </div> ) } } export default App;
dispose()
Disposes of all the resources allocated to the ActionSheet instance.
After calling this method, remove the DOM element associated with the widget:
$("#myActionSheet").dxActionSheet("dispose"); $("#myActionSheet").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-action-sheet ... *ngIf="condition"> </dx-action-sheet>
Vue
<template> <DxActionSheet ... v-if="condition"> </DxActionSheet> </template> <script> import DxActionSheet from 'devextreme-vue/action-sheet'; export default { components: { DxActionSheet } } </script>
React
import React from 'react'; import ActionSheet from 'devextreme-react/action-sheet'; function DxActionSheet(props) { if (!props.shouldRender) { return null; } return ( <ActionSheet ... > </ActionSheet> ); } class App extends React.Component { render() { return ( <DxActionSheet shouldRender="condition" /> ); } } export default App;
