Event Data

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

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

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. Inherited from RoutedEventArgs.
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. Inherited from RoutedEventArgs.

Remarks

When an annotation loses focus, the PdfViewer.AnnotationLostFocus event fires.

The PdfAnnotationGotFocusEventArgs.Annotation property gets the annotation in focus. Use the DevExpress.Pdf.PdfViewerAnnotationExtensions class methods to obtain the specific type of annotation.
