Specifying the Content Template
The template implementation depends on the used framework or library. Examples of jQuery, Angular, and ASP.NET MVC are presented below. They show how to create a template consisting of static (text) and dynamic (the Switch widget) content.
jQuery
HTML
JavaScript
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" /> <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" widget is configured here
})
)
}
});
});Angular
HTML
TypeScript
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<dx-popover
target="#image"
showEvent="dxhoverstart"
contentTemplate="popoverContent">
<div *dxTemplate="let data of 'popoverContent'">
<p>Static content</p>
<dx-switch>
<!-- The "Switch" widget is configured here -->
</dx-switch>
</div>
</dx-popover>
import { DxPopoverModule, DxSwitchModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxPopoverModule,
DxSwitchModule
],
// ...
})ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().Popover()
.Target("#image")
.ShowEvent("dxhoverstart")
.ContentTemplate(@<text>
<p>Static content</p>
@(Html.DevExtreme().Switch()
// The "Switch" widget is configured here
)
</text>)
)
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />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 option's value.
jQuery

<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<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() {
var popover = $("#popoverContainer").dxPopover({
target: "#image",
showEvent: 'dxhoverstart',
hideEvent: 'dxhoverend',
contentTemplate: 'template1'
}).dxPopover("instance");
$("#buttonContainer").dxButton({
text: "Change the Template",
onClick: function (e) {
var currentTemplate = popover.option("contentTemplate");
popover.option("contentTemplate", currentTemplate == "template1" ? "template2" : "template1");
}
});
