ArcScaleLayerCollection Class

A collection that stores the layers of a particular arc scale.

Namespace: DevExpress.UI.Xaml.Gauges

Assembly: DevExpress.UI.Xaml.Gauges.v18.2.dll

Declaration

public class ArcScaleLayerCollection :
    LayerCollection<ArcScaleLayer>,
    IOwnedElement
Public Class ArcScaleLayerCollection
    Inherits LayerCollection(Of ArcScaleLayer)
    Implements IOwnedElement

Each arc scale can hold a collection of layers returned by the ArcScale.Layers property and represented by the ArcScaleLayerCollection class. Each collection item is an instance of the ArcScaleLayer class and can be accessed via the Item[Int32] property of an ArcScaleLayerCollection object.

For more information on layers, refer to the Layers (Circular Scale) document.

Examples

The following example demonstrates how to create a Circular Gauge with two needles, three ranges, one marker and one range bar.
