Angular Popover - Customize the Title

The Popover is displayed without a title by default. To add it, set the showTitle property to true and specify the title text using the title property. The title can contain a button that closes the Popover. To enable it, assign true to the showCloseButton property.

    $("#popoverContainer").dxPopover({

        title: "Popover Title",
        showTitle: true,
        showCloseButton: true
    });

ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().Popover()
    .Target("#image")
    .ShowEvent("dxhoverstart")
    .HideEvent("dxhoverend")
    .ContentTemplate(@<text>
        <!-- ... -->

    .Title("Popover Title")
    .ShowTitle(true)
    .ShowCloseButton(true)

<img id="image" src="https://url/to/an/image" />

If you need to define the title completely, specify a template for it as shown in the following code:

jQuery
HTML
JavaScript
<img id="image" src="https://url/to/an/image" />
<div id="popoverContainer">
    <p>Popover content</p>
    <div data-options="dxTemplate: { name: 'titleTemplate' }">
        <p>Title template</p>
    </div>
</div>
$(function() {
    $("#popoverContainer").dxPopover({
        target: "#image",
        showEvent: "dxhoverstart",
        hideEvent: "dxhoverend",
        showTitle: true,
        titleTemplate: "titleTemplate"
    });
});

    titleTemplate="titleTemplate">
    <div *dxTemplate="let data of 'content'">
        <p>Popover content</p>
    </div>
    <div *dxTemplate="let data of 'titleTemplate'">
        <p>Title template</p>
    </div>
</dx-popover>

    );

class App extends React.Component {
    render() {
        return (

                <img id="image" src="https://url/to/an/image" />
                <Popover
                    showTitle={true}
                    target="#image"

You can switch title templates on the fly just as you can do with content templates. Refer to the Switching Templates On the Fly topic for more information.
