ArcGauge HtmlHelper Overview

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

The ArcGauge represents a value on a circular arc.

Initializing the ArcGauge

  1. Follow all the steps from the introductory article on Telerik UI for ASP.NET Core.
  2. Create a new action method which renders the view.

    public ActionResult Index()
    {
        return View();
    }
    
  3. Add the ArcGauge.

    @(Html.Kendo().ArcGauge()
        .Name("arcGauge") // The name of the AcrGauge is mandatory. It specifies the "id" attribute of the widget.
        .Value(65)
        .Scale(x => x.Min(0).Max(100))
        .CenterTemplate("#:value#%")
    )
    

Referencing Existing Instances

To reference an existing Telerik UI ArcGauge instance, use the jQuery.data() configuration option. Once a reference is established, use the ArcGauge API to control its behavior.

// Place the following after your Telerik UI ArcGauge for ASP.NET Core declaration.
<script>
    $(function() {
        // The Name() of the ArcGauge is used to get its client-side instance.
        var gauge = $("#arcGauge").data("kendoArcGauge");
    });
</script>
