Angular ActionSheet Methods
This section describes the members used to manipulate the widget.
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)
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> <dx-action-sheet id="actionSheet1" /> <dx-action-sheet 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.
The following code disposes of an ActionSheet instance that corresponds to the element ID (or reference variable in Angular) and removes the element from the DOM:
jQuery
$("#myActionSheet").dxActionSheet("dispose"); $("#myActionSheet").remove();
Angular
<dx-action-sheet #actionSheetVar id="myActionSheet"></dx-action-sheet>
import { ..., ViewChild } from "@angular/core"; import { DxActionSheetComponent } from "devextreme-angular"; // ... export class AppComponent { @ViewChild("actionSheetVar") actionSheet: DxActionSheetComponent; removeActionSheet (e) { this.actionSheet.instance.dispose(); document.getElementById("myActionSheet").remove(); } }
element()
Gets the root widget element.
An HTML element or a jQuery element when you use jQuery.
endUpdate()
