TimeLine Overview

The Telerik UI TimeLine TagHelper for ASP.NET Core is a server-side wrapper for the Kendo UI TimeLine widget.

The TimeLine widget displays a collection of events and their data in a chronological succession for each year.

You can scroll through the events and collapse/expand them. The events order can be vertical or horizontal, and you can customize their templates, as well as respond to events and use API control the widget behavior. You can also control the format of the rendered date for the event. If you provide a list of actions, they will be rendered as links after the description and images.

Initializing the TimeLine

The following example demonstrates how to define the TimeLine by using the TimeLine TagHelper. Note the tabs for the controller and model code that show how to feed data to the widget.

<kendo-timeline name="timeline" orientation="horizontal" datadatefield="EventDate" datatitlefield="Title" datasubtitlefield="Subtitle" datadescriptionfield="Description" dataactionsfield="Actions" dataimagesfield="Images">
    <datasource>
        <transport>

                <fields>

                </fields>
            </model>
