DevExtreme React - Overview
The Popover is a widget that shows notifications within a box with an arrow pointing to a specified UI element.
The following code creates a simple Popover on your page and attaches it to another element (in this example, to an image).
jQuery
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<div id="popoverContainer">
    <p>Popover content</p>
</div>
$(function() {
    $("#popoverContainer").dxPopover({
        target: "#image",
        showEvent: 'dxhoverstart',
        hideEvent: 'dxhoverend'
    });
});Angular
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<dx-popover
    target="#image"
    showEvent="dxhoverstart"
    hideEvent="dxhoverend">
    <div *dxTemplate="let data of 'content'">
        <p>Popover content</p>
    </div>
</dx-popover>
import { DxPopoverModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...

        DxPopoverModule
    ],
    // ...
})ASP.NET MVC Controls
@(Html.DevExtreme().Popover()
    .Target("#image")
    .ShowEvent("dxhoverstart")
    .HideEvent("dxhoverend")
    .ContentTemplate(@<text>
        <p>Popover content</p>
    </text>)
)
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />There are several ways to specify the content of the Popover. Learn more in the Customize the Content article. The Popover can also be displayed with a title and toolbars. For detailed information, see the Customize the Title and Specify Toolbar Items topics.
