This section describes methods that control the Sortable UI component.
Postpones rendering that can negatively affect performance until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.
See AlsoSpecifies the device-dependent default configuration properties for this component.
Parameters:The component's default device properties.
Object structure:
Name Type Description device |Device parameters.
When you specify a function, get information about the current device from the argument. Return true if the properties should be applied to the device.
Options to be applied.
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 Sortable UI component in an application executed on the desktop.
jQueryDevExpress.ui.dxSortable.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Sortable properties } });Angular
import Sortable, { Properties } from "devextreme/ui/sortable"; // ... export class AppComponent { constructor () { Sortable.defaultOptions<Properties>({ device: { deviceType: "desktop" }, options: { // Here go the Sortable properties } }); } }Vue
<template> <div> <DxSortable id="sortable1" /> <DxSortable id="sortable2" /> </div> </template> <script> import DxSortable from "devextreme-vue/sortable"; import Sortable from "devextreme/ui/sortable"; Sortable.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Sortable properties } }); export default { components: { DxSortable } } </script>React
import dxSortable from "devextreme/ui/sortable"; import Sortable from "devextreme-react/sortable"; dxSortable.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Sortable properties } }); export default function App() { return ( <div> <Sortable id="sortable1" /> <Sortable id="sortable2" /> </div> ) }
You can also set rules for multiple device types:
jQueryconst devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { DevExpress.ui.dxSortable.defaultOptions({ device: deviceConfig, options: { // Here go the Sortable properties } }); });Angular
import Sortable, { Properties } from "devextreme/ui/sortable"; // ... export class AppComponent { constructor () { const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { Sortable.defaultOptions<Properties>({ device: deviceConfig, options: { // Here go the Sortable properties } }); }); } }Vue
<template> <div> <DxSortable /> </div> </template> <script> import DxSortable from "devextreme-vue/sortable"; import Sortable from "devextreme/ui/sortable"; const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { Sortable.defaultOptions({ device: deviceConfig, options: { // Here go the Sortable properties } }); }); export default { components: { DxSortable } } </script>React
import dxSortable from "devextreme/ui/sortable"; import Sortable from "devextreme-react/sortable"; const devicesConfig = [ { deviceType: 'desktop' }, { deviceType: 'tablet' }, { deviceType: 'phone' }, ]; devicesConfig.forEach(deviceConfig => { dxSortable.defaultOptions({ device: deviceConfig, options: { // Here go the Sortable properties } }); }); export default function App() { return ( <div> <Sortable /> </div> ) }
Disposes of all the resources allocated to the Sortable instance.
jQueryAfter calling this method, remove the DOM element associated with the UI component:
$("#mySortable").dxSortable("dispose"); $("#mySortable").remove();Angular
Use conditional rendering instead of this method:
<dx-sortable ... *ngIf="condition"> </dx-sortable>Vue
Use conditional rendering instead of this method:
<template> <DxSortable ... v-if="condition"> </DxSortable> </template> <script> import DxSortable from 'devextreme-vue/sortable'; export default { components: { DxSortable } } </script>React
Use conditional rendering instead of this method:
import React from 'react'; import Sortable from 'devextreme-react/sortable'; function DxSortable(props) { if (!props.shouldRender) { return null; } return ( <Sortable ... > </Sortable> ); } class App extends React.Component { render() { return ( <DxSortable shouldRender="condition" /> ); } } export default App;
Gets the root UI component element.
Refreshes the UI component after a call of the beginUpdate() method.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.
See AlsoGets the instance of a UI component found using its DOM node.
Parameters:The UI component's container.
The UI component's instance.
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the Sortable instance found in an element with the mySortable
ID:
// Modular approach import Sortable from "devextreme/ui/sortable"; ... let element = document.getElementById("mySortable"); let instance = Sortable.getInstance(element) as Sortable; // Non-modular approach let element = document.getElementById("mySortable"); let instance = DevExpress.ui.dxSortable.getInstance(element);See Also
