Specifying the Content Template
The following code shows how to create a template consisting of static (text) and dynamic (the Switch UI component) content:
jQuery
HTML
JavaScript
<img id="image" src="https://url/to/an/image" /> <div id="popoverContainer"></div>
$(function() { $("#popoverContainer").dxPopover({ target: "#image", showEvent: 'dxhoverstart', contentTemplate: function (contentElement) { contentElement.append( $("<p />").text("Static Content"), $("<div />").attr("id", "switchContainer").dxSwitch({ // The "Switch" UI component is configured here }) ) } }); });
Angular
HTML
TypeScript
<img id="image" src="https://url/to/an/image" /> <dx-popover target="#image" showEvent="dxhoverstart" contentTemplate="popoverContent"> <div *dxTemplate="let data of 'popoverContent'"> <p>Static content</p> <dx-switch> <!-- The "Switch" UI component is configured here --> </dx-switch> </div> </dx-popover>
import { DxPopoverModule, DxSwitchModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxPopoverModule, DxSwitchModule ], // ... })
Vue
<template> <div> <img id="image" src="https://url/to/an/image" /> <DxPopover target="#image" show-event="dxhoverstart"> <template> <p>Static content</p> <dx-switch> <!-- The "Switch" UI component is configured here --> </dx-switch> </template> </DxPopover> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxPopover } from 'devextreme-vue/popover'; import { DxSwitch } from 'devextreme-vue/switch'; export default { components: { DxPopover, DxSwitch } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Popover } from 'devextreme-react/popover'; import { Switch } from 'devextreme-react/switch'; const renderContent = () => { return ( <p>Static content</p> <Switch> {/* The "Switch" UI component is configured here */} </Switch> ); } class App extends React.Component { render() { return ( <div> <img id="image" src="https://url/to/an/image" /> <Popover target="#image" showEvent="dxhoverstart" contentRender={renderContent} /> </div> ); } } export default App;
ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().Popover() .Target("#image") .ShowEvent("dxhoverstart") .ContentTemplate(@<text> <p>Static content</p> @(Html.DevExtreme().Switch() // The "Switch" UI component is configured here ) </text>) ) <img id="image" src="https://url/to/an/image" />
Switching Templates On the Fly
If you need to render different templates depending on a specific condition, define them inside the Popover container using the DevExtreme dxTemplate markup component. You can switch the templates on the fly by changing the contentTemplate property's value.
jQuery
HTML
JavaScript
CSS
<img id="image" src="https://url/to/an/image" /> <div id="buttonContainer"></div> <div id="popoverContainer"> <div data-options="dxTemplate: { name: 'template1' }"> <p>First template</p> </div> <div data-options="dxTemplate: { name: 'template2' }"> <p>Second template</p> </div> </div>
$(function() { const popover = $("#popoverContainer").dxPopover({ target: "#image", showEvent: 'dxhoverstart', hideEvent: 'dxhoverend', contentTemplate: 'template1' }).dxPopover("instance"); $("#buttonContainer").dxButton({ text: "Change the Template", onClick: function (e) { const currentTemplate = popover.option("contentTemplate"); popover.option("contentTemplate", currentTemplate == "template1" ? "template2" : "template1"); } }); });
#buttonContainer { display: block; width: 200px }
Angular
HTML
TypeScript
CSS
<img id="image" src="https://url/to/an/image" /> <dx-button id="buttonContainer" text="Change the Template" (onClick)="changeTemplate()"> </dx-button> <dx-popover target="#image" showEvent="dxhoverstart" hideEvent="dxhoverend" [contentTemplate]="currentTemplate"> <div *dxTemplate="let data of 'template1'"> <p>First template</p> </div> <div *dxTemplate="let data of 'template2'"> <p>Second template</p> </div> </dx-popover>
import { DxPopoverModule, DxButtonModule } from "devextreme-angular"; // ... export class AppComponent { currentTemplate: string = "template1"; changeTemplate () { this.currentTemplate = (this.currentTemplate == 'template1' ? 'template2' : 'template1') } } @NgModule({ imports: [ // ... DxPopoverModule, DxButtonModule ], // ... })
#buttonContainer { display: block; width: 200px }
Vue
App.vue
<template> <div> <img id="image" src="https://url/to/an/image" /> <DxPopover target="#image" show-event="dxhoverstart" hide-event="dxhoverend" :contentTemplate="currentTemplate"> <template #template1> <p>First template</p> </template> <template #template2> <p>Second template</p> </template> </DxTooltip> <DxButton id="buttonContainer" text="Change the Template" @click="changeTemplate" /> </div> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxPopover } from 'devextreme-vue/popover'; import { DxButton } from 'devextreme-vue/button'; export default { components: { DxPopover, DxButton }, data() { return { currentTemplate: "template1" }; }, methods: { changeTemplate () { this.currentTemplate = (this.currentTemplate === 'template1' ? 'template2' : 'template1') } } } </script> <style> #buttonContainer { display: block; width: 200px } </style>
