Getting Started with the TabStrip
This tutorial explains how to set up a basic Telerik UI for ASP.NET Core TabStrip and highlights the major steps in the configuration of the component.
You will initialize a TabStrip component with several items and a basic content definition. Finally, you can run the sample code in Telerik REPL and continue exploring the components.
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 the following guide:
- Creating a new pre-configured project for the Telerik UI for ASP.NET Core components from a project template.
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>TabStrip with cities</h4>
<div>
</div>
@addTagHelper *, Kendo.Mvc
<h4>TabStrip with cities</h4>
<div>
</div>
2. Initialize the TabStrip
Use the TabStrip HtmlHelper or TagHelper to add the component to a page:
- The
Name()configuration method is mandatory as its value is used for theidand the name attributes of the TabStrip element. - The
Selected()configuration of a TabStrip's item specifies which tab is selected initially. - The
Image()property of a TabStrip's item determines the icon or logo path in front of its text.
@using Kendo.Mvc.UI
<h4>TabStrip with cities</h4>
<div>
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Selected(true)
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png"))
.Content(@<text>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</text>);
tabstrip.Add().Text("New York")
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png"))
.Content(@<text>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</text>);
})
)
</div>
@addTagHelper *, Kendo.Mvc
<h4>TabStrip with cities</h4>
<div>
<kendo-tabstrip name="tabstrip">
<items>
<tabstrip-item text="Paris" selected="true"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png")">
<content>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</content>
</tabstrip-item>
<tabstrip-item text="New York"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png")">
<content>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</content>
</tabstrip-item>
</items>
</kendo-tabstrip>
</div>
3. Setting the Tab Position
The next step is to demonstrate how you can set the TabPosition() option which allows you to dictate where the tabs are rendered. The default setting is Top, but you can also use Left, Bottom, etc.
@using Kendo.Mvc.UI
<h4>TabStrip with cities</h4>
<div>
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.TabPosition(TabStripTabPosition.Top)
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Selected(true)
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png"))
.Content(@<text>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</text>);
tabstrip.Add().Text("New York")
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png"))
.Content(@<text>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</text>);
})
)
</div>
@addTagHelper *, Kendo.Mvc
<h4>TabStrip with cities</h4>
<div>
<kendo-tabstrip name="tabstrip" tab-position="top">
<items>
<tabstrip-item text="Paris" selected="true"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png")">
<content>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</content>
</tabstrip-item>
<tabstrip-item text="New York"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png")">
<content>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</content>
</tabstrip-item>
</items>
</kendo-tabstrip>
</div>
4. Handle a TabStrip Event
The TabStrip component provides convenient events for implementing your desired logic. In this tutorial, you will use the exposed Select() event to log a new entry in the browser's console.
@using Kendo.Mvc.UI
<h4>TabStrip with cities</h4>
<div>
<script>
function select(e) {
console.log("Selected old value :: " + this.value());
}
</script>
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.TabPosition(TabStripTabPosition.Top)
.Events(e=>e.Select("select"))
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Selected(true)
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png"))
.Content(@<text>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</text>);
tabstrip.Add().Text("New York")
.ImageUrl(Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png"))
.Content(@<text>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</text>);
})
)
</div>
@addTagHelper *, Kendo.Mvc
<h4>TabStrip with cities</h4>
<div>
<script>
function select(e) {
console.log("Selected old value :: " + this.value());
}
</script>
<kendo-tabstrip name="tabstrip" tab-position="top" on-select="select">
<items>
<tabstrip-item text="Paris" selected="true"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/photo.png")">
<content>
<div class="weather">
<h2>17<span>ºC</span></h2>
<p>Rainy weather in Paris.</p>
</div>
<span class="rainy"> </span>
</content>
</tabstrip-item>
<tabstrip-item text="New York"
image-url="@Url.Content("https://demos.telerik.com/aspnet-core/shared/icons/16/star.png")">
<content>
<div class="weather">
<h2>29<span>ºC</span></h2>
<p>Sunny weather in New York.</p>
</div>
<span class="sunny"> </span>
</content>
</tabstrip-item>
</items>
</kendo-tabstrip>
</div>
5. (Optional) Reference Existing TabStrip Instances
You can reference the TabStrip 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 tabstripReference = $("#tabstrip").data("kendoTabStrip"); // tabstripReference is a reference to the existing TabStrip instance of the helper. </script> -
Use the TabStrip client-side API to control the behavior of the widget. In this example, you will use the
selectmethod to select an item.<script> var tabstripReference = $("#tabstrip").data("kendoTabStrip"); // tabstripReference is a reference to the existing TabStrip instance of the helper. tabstripReference.select(3); </script>
