Angular Tooltip - Overview

The Tooltip UI component displays a tooltip for a specified element on the page.

View Demo

The following code creates a simple Tooltip on your page and attaches it to another element (in this example, to an image).

JavaScript
<img id="image" src="https://url/to/an/image" />
<div id="tooltipContainer"></div>
$(function() {
    $("#tooltipContainer").dxTooltip({
        target: "#image",
        showEvent: 'dxhoverstart',
        hideEvent: 'dxhoverend',
        contentTemplate: function (contentElement) {
            contentElement.append(
                $("<p />").text("Tooltip content")
            )
        }
    });
});

<img id="image" src="https://url/to/an/image" />
<dx-tooltip
    target="#image"

    hideEvent="dxhoverend">
    <div *dxTemplate="let data of 'content'">
        <p>Tooltip content</p>

                    hideEvent="dxhoverend"
                    contentRender={renderContent}

ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().Tooltip()
    .Target("#image")
    .ShowEvent("dxhoverstart")
    .HideEvent("dxhoverend")
    .ContentTemplate(@<text>
        <p>Tooltip content</p>
    </text>)
)
<img id="image" src="https://url/to/an/image" />
NOTE

The component may affect the page layout when used inside a flex container with other elements. For example, the following parent CSS styles can cause this issue:

CSS
.flex {
    display: flex;
    justify-content: space-between;
}

To avoid changes to the page layout, implement the following CSS styles for the Tooltip container:

CSS
.dx-tooltip {
    display: none !important;
}
