ScrollView Overview
The Telerik UI ScrollView TagHelper for ASP.NET Core is a server-side wrapper for the Kendo UI ScrollView widget.
The ScrollView displays a horizontal collection of content or image views with built-in navigation between them. It can be scrolled through dragging, gestures, arrow click or page click or tap. Among the key features of the ScrollView are data-source binding, customizable template, built-in pager, adjustable bounce effects and scroll velocity.
Initializing the ScrollView
You can initialize the ScrollView either from HTML or from a data source with a template.
From HTML
- Use its
itemstag. - Define the content for each page.
<kendo-scrollview name="scrollView" content-height="100%" template-id="scrollview-template" style="height:600px; width:890px; max-width: 100%;">
<items>
<scrollview-item>
<content><h1>One</h1></content>
</scrollview-item>
<scrollview-item>
<content><h1>Two</h1></content>
</scrollview-item>
<scrollview-item>
<content><h1>Three</h1></content>
</scrollview-item>
</items>
</kendo-scrollview>
<style>
h1 {
margin-top: 30%;
text-align:center;
}
</style>
From the Data Source
- Create a Kendo UI for jQuery template.
- Use the
template-idproperty to pass it and provide a DataSource.
Make sure that the template provides the pageSize of the data source. If serverPaging is enabled, the ScrollView will request the data in advance so it becomes available before it is required, thus improving user experience. The ScrollView uses virtualization when it is bound to a data source and it only has three pages at all times—the current, the previous, and the next.
<kendo-scrollview name="scrollView" content-height="100%" template-id="scrollview-template" style="height:600px; width:890px; max-width: 100%;">
<datasource custom-type="odata" page-size="3" server-paging="true">
<transport>
<read url="https://demos.telerik.com/kendo-ui/service/Northwind.svc/Products" />
</transport>
</datasource>
</kendo-scrollview>
<script id="scrollview-template" type="text/x-kendo-template">
<div class="img-wrapper">
# for (var i = 0; i < data.length; i++) { #
<div>
<div style="width: 140px; height: 140px; background-image: #=setBackground(data[i].ProductID)#; background-repeat:no-repeat; background-size: cover;"></div>
<p>#= data[i].ProductName #</p>
</div>
# } #
</div>
