CheckEdit.Indeterminate Event

Occurs when a check editor is set to the indeterminate state.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

#Declaration

public event RoutedEventHandler Indeterminate

#Event Data

The Indeterminate 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

A check editor can be set to the indeterminate state if its CheckEdit.IsThreeState property is set to true. Handle the Indeterminate event to respond to setting a check editor to the indeterminate state.

To programmatically set the editor to the indeterminate state, set its CheckEdit.IsChecked property to null.
