JavaScript/jQuery TileView Options
An object defining configuration properties for the TileView UI component.
accessKey
Specifies the shortcut key that sets focus on the UI component.
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
Specifies whether the UI component changes its state as a result of user interaction.
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components. See the following GitHub repository for an example of this type of platform: MUI.
baseItemHeight
Specifies the height of the base tile view item.
The actual item height equals the heightRatio field value of an item multiplied by the value of this property.
baseItemWidth
Specifies the width of the base tile view item.
The actual item width equals the widthRatio value of an item multiplied by the value of this property.
dataSource
Binds the UI component to data.
The TileView works with collections of string
values or objects.
Depending on your data source, bind the TileView to data as follows. If the data source provides objects, also specify the itemTemplate. You can skip this part if the objects contain fields described in the items section.
Data Array
Assign the array to the dataSource option.Read-Only Data in JSON Format
Set the dataSource property to the URL of a JSON file or service that returns JSON data.OData
Implement an ODataStore.Web API, PHP, MongoDB
Use one of the following extensions to enable the server to process data according to the protocol DevExtreme UI components use:Then, use the createStore method to configure access to the server on the client as shown below. This method is part of DevExtreme.AspNet.Data.
jQuery
JavaScript$(function() { let serviceUrl = "https://url/to/my/service"; $("#tileViewContainer").dxTileView({ // ... dataSource: DevExpress.data.AspNet.createStore({ key: "ID", loadUrl: serviceUrl + "/GetAction", insertUrl: serviceUrl + "/InsertAction", updateUrl: serviceUrl + "/UpdateAction", deleteUrl: serviceUrl + "/DeleteAction" }) }) });

Any other data source
Implement a CustomStore.
Regardless of the data source on the input, the TileView always wraps it in the DataSource object. This object allows you to sort, filter, group, and perform other data shaping operations. To get its instance, call the getDataSource() method.
Review the following notes about data binding:
Do not specify the items property if you specified the dataSource, and vice versa.
Data field names cannot be equal to
this
and should not contain the following characters:.
,:
,[
, and]
.The stores and DataSource have methods to process and update data. However, the methods do not allow you to perform particular tasks (for example, replace the entire dataset, reconfigure data access at runtime). For such tasks, create a new array, store, or DataSource and assign it to the dataSource property as shown in the articles about changing properties in jQuery, Angular, React, and Vue.
disabled
Specifies whether the UI component responds to user interaction.
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#tileViewContainer").dxTileView({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-tile-view ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-tile-view>
import { DxTileViewModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxTileViewModule ], // ... })
Vue
<template> <DxTileView ... :element-attr="tileViewAttributes"> </DxTileView> </template> <script> import DxTileView from 'devextreme-vue/tile-view'; export default { components: { DxTileView }, data() { return { tileViewAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import TileView from 'devextreme-react/tile-view'; class App extends React.Component { tileViewAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <TileView ... elementAttr={this.tileViewAttributes}> </TileView> ); } } export default App;
focusStateEnabled
Specifies whether the UI component can be focused using keyboard navigation.
height
Specifies the UI component's height.
This property accepts a value of one of the following types:
Number
The height in pixels.String
A CSS-accepted measurement of height. For example,"55px"
,"80%"
,"inherit"
.Function
A function returning either of the above. For example:JavaScriptheight: function() { return window.innerHeight / 1.5; }
"auto"
.hint
Specifies text for a hint that appears when a user pauses on the UI component.
hoverStateEnabled
Specifies whether the UI component changes its state when a user pauses on it.
itemHoldTimeout
The time period in milliseconds before the onItemHold event is raised.
items[]
An array of items displayed by the UI component.
Array<String | dxTileViewItem | any>
The items array can contain:
- Strings
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
tileViewInstance.option('items', newItems);
As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
noDataText
Specifies the text or HTML markup displayed by the UI component if the item collection is empty.
The TileView component evaluates the noDataText property's value. This evaluation, however, makes the TileView potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the noDataText property. Refer to the following help topic for more information: Potentially Vulnerable API - noDataText.

Angular
<dx-tile-view ... (onOptionChanged)="handlePropertyChange($event)"> </dx-tile-view>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... handlePropertyChange(e) { if(e.name === "changedProperty") { // handle the property change here } } }

Number
The width in pixels.String
A CSS-accepted measurement of width. For example,"55px"
