Getting Started with the SkeletonContainer
This tutorial explains how to set up a basic Telerik UI for ASP.NET Core SkeletonContainer and highlights the major steps in the configuration of the component.
You will initialize a SkeletonContainer component.
Finally, you can run the sample code in Telerik REPL and continue exploring the component.
Prerequisites
To successfully complete the tutorial, you need a project that is already configured to use the Telerik UI for ASP.NET Core components:
You can use the Telerik REPL playground and skip installing the components on your system and configuring a project.
-
You can prepare a Visual Studio project by following either of these guides:
Creating a new pre-configured project for the Telerik UI for ASP.NET Core components from a project template.
Manually configuring an existing project as described in the First Steps on Windows or First Steps on Mac articles.
1. Prepare the CSHTML File
The first step is to add the required directives at the top of the .cshtml document:
-
To use the Telerik UI for ASP.NET Core HtmlHelpers:
@using Kendo.Mvc.UI -
To use the Telerik UI for ASP.NET Core TagHelpers:
@addTagHelper *, Kendo.Mvc
Optionally, you can structure the document by adding the desired HTML elements like headings, divs, paragraphs, and others.
@using Kendo.Mvc.UI
<h4>SkeletonContainer</h4>
@addTagHelper *, Kendo.Mvc
<h4>SkeletonContainer</h4>
2. Initialize the SkeletonContainer
Use the SkeletonContainer HtmlHelper or TagHelper to add the component to a page:
- The
Name()configuration method is mandatory as its value is used for theidand thenameattributes of the SkeletonContainer element. - The
Template()configuration method defines a template that will be used to visualize the skeleton shapes..

3. Use the Animation Configuration of the SkeletonContainer
The next step is to configure Animation configuration. The Animation configuration defines a value determining whether the items will be animated.
@using Kendo.Mvc.UI
<h4>SkeletonContainer</h4>
@section HeadContent
{
<style>
.k-card-header {
display: flex;
height: 70px;
}
.user-info {
padding-left: 10px;
}
.cards-container {
display: flex;
flex-wrap: wrap;
justify-content: center;
}
.cards-container > div {
margin: 5%;
}
.cards-container .k-card .k-card-subtitle {
margin-top: 5px;
}
.avatar {
border-radius: 50%;
width: 40px;
height: 40px;
}
.k-card {
width: 340px;
height: 350px;
}
.k-card-footer {
text-align: center;
}
</style>
}
<div class="cards-container">
@(Html.Kendo().SkeletonContainer()
.Name("skeleton")
.Animation(SkeletonContainerAnimation.Pulse)
.Template("<div class='k-card'>" +
"<div class='k-card-header'>" +
"<div>" +
"<span data-shape-circle class='k-card-media avatar'></span>" +
"</div>" +
"<div class='user-info' style='width: 100%;'>" +
"<span data-shape-text class='k-card-title'></span>" +
"<span data-shape-text class='k-card-subtitle' style='width: 35%;'></span>" +
"</div>" +
"</div>" +
"<span data-shape-rectangle style='width: 340px; height: 225px; '></span>" +
"<div class='k-card-body'>" +
"<span data-shape-text></span>" +
"</div>" +
"</div>")
)
<div class="k-card">
<div class="k-card-header">
<div style="width:40px; height:40px;">
<img alt="Telerik UI for ASP.NET Core SkeletonContainer avatar" class="k-card-media avatar" src="@Url.Content("~/shared/web/skeleton/avatar.jpg")" />
</div>
<div class="user-info">

flex-wrap: wrap;
justify-content: center;
}
.cards-container > div {
margin: 5%;
}
.cards-container .k-card .k-card-subtitle {

}
.avatar {

)
<div class="k-card">
<div class="k-card-header">

</div>
</div>
5. (Optional) Reference Existing SkeletonContainer Instances
You can reference the SkeletonContainer instances that you have created and build on top of their existing configuration:
-
Use the
idattribute of the component instance to establish a reference.<script> var skeletoncontainer = $("#skeleton").data("kendoSkeletonContainer"); // skeletoncontainer is a reference to the existing skeletoncontainer instance of the helper. </script>
