ValueIndicatorBase.Value Property

Gets or sets the value of a scale indicator.

Namespace: DevExpress.Xpf.Gauges

Assembly: DevExpress.Xpf.Gauges.v23.2.dll

NuGet Package: DevExpress.Wpf.Gauges

Declaration

C#

public double Value { get; set; }

VB.NET

Public Property Value As Double

Property Value

Type	Description
Double	Specifies the position of a value indicator on the scale.

Remarks

The Value property of the value indicator can be changed not only programmatically, but also by end-users via mouse-clicks. This capability becomes available after setting the ValueIndicatorBase.IsInteractive property to true.

Snap Indicator Values to Tickmarks

When users change the indicator value, they can set any value. You can prohibit users from setting values bettween tickmarks. Set the ValueIndicatorBase.SnapMode property to MajorTickmarks / MinorTickmarks to snap the indicator value to major/minor tickmarks.

Example

This example illustrates how to create a CircularGaugeControl instance with a single ArcScale object.
