Slider HtmlHelper Overview

The Telerik UI Slider HtmlHelper for ASP.NET MVC is a server-side wrapper for the Kendo UI Slider widget.

The Slider provides a rich input for selecting numeric values nd can be either a Slider which presents one handle and two opposing buttons for selecting a single numeric value or a Slider which presents two handlers for defining a range of numeric values.

Basic Configuration

  1. Make sure you followed all the steps from the introductory article on Telerik UI for ASP.NET MVC.
  2. Create a new action method which renders the view.

    public ActionResult Index()
    {
        return View();
    }
    
  3. Add a Slider.

        <%: Html.Kendo().Slider()
            .Name("slider") // The name of the Slider is mandatory. It specifies the "id" attribute of the Slider.
            .Min(0) // Set min value of the Slider.
            .Max(100) // Set min value of the Slider.
            .Value(20) // Set the value of the Slider.
        %>
    
        @(Html.Kendo().Slider()
            .Name("slider") // The name of the Slider is mandatory. It specifies the "id" attribute of the Slide.
            .Min(0) // Set min value of the Slider.
            .Max(100) // Set min value of the Slider.
            .Value(20) // Set the value of the Slider.
        )
    

Events

You can subscribe to all Slider events.For a complete example on basic Slider events, refer to the demo on using the events of the Slider.

Handling by Handler Name

The following example demonstrates how to subscribe to events by a handler name.

    <%: Html.Kendo().Slider()
            .Name("slider")
            .Events(e => e
                .Change("change")
                .Slide("slide")
            )
    %>
    <script>
        function change() {
            // Handle the change event.
        }

        function slide() {
            // Handle the slide event.
        }
    </script>
    @(Html.Kendo().Slider()
            .Name("slider")
            .Events(e => e
                .Change("change")
                .Slide("slide")
            )
    )
    <script>
        function change() {
            // Handle the change event.
        }

        function slide() {
            // Handle the slide event.
        }
    </script>

Handling by Template Delegate

The following example demonstrates how to subscribe to events by a template delegate.

@(Html.Kendo().Slider()
    .Name("slider")
    .Events(e => e
        .Change(@<text>
            function() {
                // Handle the change event inline.
            }
        </text>)
        .Slide(@<text>
            function() {
                // Handle the slide event inline.
            }
        </text>)
    )
)

Referencing Existing Instances

To reference an existing Slider instance, use the jQuery.data() configuration option. Once a reference is established, use the Slider client-side API to control its behavior.

// Place the following after the Slider for ASP.NET MVC declaration.
<script>
    $(function() {
        // The Name() of the Slider is used to get its client-side instance.
        var slider = $("#slider").data("kendoSlider");
    });
</script>
