ValueIndicatorBase.IsInteractive Property

Gets or sets a value that indicates whether interactivity is enabled for the current value indicator.

Namespace: DevExpress.Xpf.Gauges

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

NuGet Package: DevExpress.Wpf.Gauges

Declaration

C#

public bool IsInteractive { get; set; }

VB.NET

Public Property IsInteractive As Boolean

Property Value

Type	Description
Boolean	true to enable interactivity; otherwise, false.

Remarks

After the IsInteractive property is set to true, it becomes possible to change an indicator’s value property via a mouse click.

Snap Indicator Values to Tickmarks

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

Example

This example demonstrates how to use animation effects in DXGauges.

To activate animation, set the GaugeControlBase.EnableAnimation property to True. After that, it becomes possible to customize the animation’s duration and easing function via its IndicatorAnimation.Duration and IndicatorAnimation.EasingFunction properties.
