Namespace: DevExpress.Xpf.Core

Assembly: DevExpress.Xpf.Core.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public event RoutedEventHandler Unchecked

VB.NET

Public Event Unchecked As RoutedEventHandler

Event Data

The Unchecked event's data class is RoutedEventArgs. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.
Source	Gets or sets a reference to the object that raised the event.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.

Remarks

This property is in effect if the button’s SimpleButton.ButtonKind property is set to ButtonKind.Toggle.

The Unchecked event is raised after the button has been set to the unchecked state by an end-user or in code by setting the SimpleButton.IsChecked property to false.
