React TileView Methods
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 TileView UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxTileView.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the TileView properties } });
Angular
import TileView from "devextreme/ui/tile_view"; // ... export class AppComponent { constructor () { TileView.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the TileView properties } }); } }
Vue
<template> <div> <DxTileView id="tileView1" /> <DxTileView id="tileView2" /> </div> </template> <script> import DxTileView from "devextreme-vue/tile-view"; import TileView from "devextreme/ui/tile_view"; TileView.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the TileView properties } }); export default { components: { DxTileView } } </script>
React
import React, {useEffect} from "react"; import dxTileView from "devextreme/ui/tile_view"; import TileView from "devextreme-react/tile-view"; export default function App() { useEffect(() => { dxTileView.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the TileView properties } }) }); return ( <div> <TileView id="tileView1" /> <TileView id="tileView2" /> </div> ) }
dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myTileView").dxTileView("dispose"); $("#myTileView").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-tile-view ... *ngIf="condition"> </dx-tile-view>
Vue
<template> <DxTileView ... v-if="condition"> </DxTileView> </template> <script> import DxTileView from 'devextreme-vue/tile-view'; export default { components: { DxTileView } } </script>
React
import React from 'react'; import TileView from 'devextreme-react/tile-view'; function DxTileView(props) { if (!props.shouldRender) { return null; } return ( <TileView ... > </TileView> ); } class App extends React.Component { render() { return ( <DxTileView shouldRender="condition" /> ); } } export default App;

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the TileView instance found in an element with the myTileView
ID:
// Modular approach import TileView from "devextreme/ui/tile_view"; ... let element = document.getElementById("myTileView"); let instance = TileView.getInstance(element) as TileView; // Non-modular approach let element = document.getElementById("myTileView"); let instance = DevExpress.ui.dxTileView.getInstance(element);

registerKeyHandler(key, handler)
A handler. Accepts the keydown event as the argument. It is a dxEvent or a jQuery.Event when you use jQuery.
The key argument accepts one of the following values:

- "enter"
- "escape"
- "pageUp"
- "pageDown"
