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.

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.

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.
