JavaScript/jQuery Resizable Methods
Methods of the DomComponent object.
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.

defaultOptions is a static method that the widget class supports. The following code demonstrates how to specify default options for all instances of the Resizable widget in an application executed on the desktop.
jQuery
DevExpress.ui.dxResizable.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Resizable options } });
Angular
import Resizable from 'devextreme/ui/resizable'; // ... export class AppComponent { constructor () { Resizable.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Resizable options } }); } }
dispose()
Disposes of all the resources allocated to the Resizable instance.
The following code disposes of an Resizable instance that corresponds to the element ID (or reference variable in Angular) and removes the element from the DOM:
jQuery
$("#myResizable").dxResizable("dispose"); $("#myResizable").remove();
Angular
<dx-resizable #resizableVar id="myResizable"></dx-resizable>
import { ..., ViewChild } from "@angular/core"; import { DxResizableComponent } from "devextreme-angular"; // ... export class AppComponent { @ViewChild("resizableVar") resizable: DxResizableComponent; removeResizable (e) { this.resizable.instance.dispose(); document.getElementById("myResizable").remove(); } }
