Angular TabPanel API
The TabPanel is a widget consisting of the Tabs and MultiView widgets. It automatically synchronizes the selected tab with the currently displayed view and vice versa.
DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.
The following code shows how to create the TabPanel widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
jQuery
var tabs = [{ title: 'Tab 1 Title', text: 'Tab 1 Text Content' }, { title: 'Tab 2 Title', text: 'Tab 2 Text Content' }, { title: 'Tab 3 Title', text: 'Tab 3 Text Content' }]; $(function () { $("#tabPanel").dxTabPanel({ items: tabs }); });
<div id="tabPanel"></div>
Angular
<dx-tab-panel [items]="tabs"></dx-tab-panel>
import { DxTabPanelModule } from 'devextreme-angular' // ... export class AppComponent { tabs = [{ title: 'Tab 1 Title', text: 'Tab 1 Text Content' }, { title: 'Tab 2 Title', text: 'Tab 2 Text Content' }, { title: 'Tab 3 Title', text: 'Tab 3 Text Content' }]; } @NgModule({ imports: [ // ... DxTabPanelModule ], // ... })
AngularJS
<div ng-controller="DemoController"> <div dx-tab-panel="{ items: tabs }"></div> </div>
angular.module("DemoApp", ["dx"]) .controller("DemoController", function ($scope) { $scope.tabs = [{ title: 'Tab 1 Title', text: 'Tab 1 Text Content' }, { title: 'Tab 2 Title', text: 'Tab 2 Text Content' }, { title: 'Tab 3 Title', text: 'Tab 3 Text Content' }]; });
Knockout
<div data-bind="dxTabPanel: { items: tabs }"></div>
var viewModel = { tabs: [{ title: 'Tab 1 Title', text: 'Tab 1 Text Content' }, { title: 'Tab 2 Title', text: 'Tab 2 Text Content' }, { title: 'Tab 3 Title', text: 'Tab 3 Text Content' }] }; ko.applyBindings(viewModel);
ASP.NET MVC Controls
@(Html.DevExtreme().TabPanel() .ID("tabPanel") .Items(items => { items.Add().Title("Tab 1 Title").Text("Tab 1 Text Content"); items.Add().Title("Tab 2 Title").Text("Tab 2 Text Content"); items.Add().Title("Tab 3 Title").Text("Tab 3 Text Content"); }) )
@(Html.DevExtreme().TabPanel() _ .ID("tabPanel") _ .Items(Sub(items) items.Add().Title("Tab 1 Title").Text("Tab 1 Text Content") items.Add().Title("Tab 2 Title").Text("Tab 2 Text Content") items.Add().Title("Tab 3 Title").Text("Tab 3 Text Content") End Sub) )
