Badge Overview
The Badge is an absolutely positioned element that is used to decorate avatars, navigation menus, or other components in the application when the visual notification is needed.
It also provides customizing its content through templates, setting different types and layouts.
Initializing the Badge
The following example demonstrates how to define the Badge by using the Badge HtmlHelper.
<a class="k-button">
@(Html.Kendo().Badge()
.Name("badge")
.Value("42")
.Appearance("rectangle"))
</a>
Basic Configuration
The badge also provides the choice to be inline or overlay and set its type. To make the badge overlay add the k-badge-overlay class to the parent parent element.
<a class="k-button k-badge-overlay">
@(Html.Kendo().Badge()
.Name("badge")
.Value("42")
.Type("warning")
.Appearance("rectangle"))
</a>
Using templates
With the badge you can customize the content using templates.
<a class="k-button k-badge-overlay">
@(Html.Kendo().Badge()
.Name("badge")
.Value("42")
.Template("#= +value > 10 ? '9+' : value #")
.Appearance("rectangle"))
</a>
Referencing Existing Instances
You can access an existing Button instance by using the jQuery.data() method which gets executed by the jQuery object of the originating element. Once the reference is established, use the Badge client-side API to control its behavior.
<a class="k-button k-badge-overlay">
@(Html.Kendo().Badge()
.Name("badge")
.Value("42")
.Template("#= +value > 10 ? '9+' : value #")
.Appearance("rectangle"))
</a>
<script>
var badge = $('#badge').data('kendoBadge');
</script>
