The Telerik UI Slider TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI Slider widget.

The Slider provides a rich input for selecting numeric values. The Slider can either present one handle and two opposing buttons for selecting a single numeric value, or two handlers for defining a range of numeric values. Unlike the HTML5 range input, the Slider enables the consistent experience across browsers and delivers rich API calls and event models.

        .Max(100) // Set min value of the Slider.
        .Value(20) // Set the value of the Slider.


    <kendo-slider name="slider"
