Occurs when a toggle switch editor is set to the indeterminate state.
public event RoutedEventHandler Indeterminate
Public Event Indeterminate As RoutedEventHandler
The Indeterminate event's data class is RoutedEventArgs. The following properties provide information specific to this event:
|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:
|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.|
A toggle switch editor can be set to the indeterminate state if its ToggleSwitchEdit.IsThreeState property is set to true. Handle the Indeterminate event to respond to setting a toggle switch editor to the indeterminate state.
To programmatically set the editor to the indeterminate state, set its ToggleSwitchEdit.IsChecked property to null.
