  NameDescription
Public propertyHandledGets 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.)
Public propertyOriginalSourceGets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)
Public propertyRoutedEventGets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.)
Public propertySourceGets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)
Public propertyTargetObjectGets the object that should be made visible in response to the event.
Public propertyTargetRectGets the rectangular region in the object's coordinate space which should be made visible.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodInvokeEventHandlerInvokes event handlers in a type-specific way, which can increase event system efficiency. (Overrides RoutedEventArgs.InvokeEventHandler(Delegate, Object).)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnSetSourceWhen 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.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The FrameworkElement.RequestBringIntoView event is raised by elements when you call BringIntoView from that element. Generally, this routed event is not handled by the source. Intermediate classes that do not implement scrollable regions or similar concepts that clip content should not handle the event. The event should be permitted to bubble to parent elements that implement a scrollable region or otherwise specify ClipToBounds false. Such parent elements typically provide class handling for the RequestBringIntoView event, which is where the necessary rendering logic occurs whenever a given element requests that it be made viewable within the clipping region.

Content elements can cause the event to be raised by their content hosts (through calling BringIntoView and raising FrameworkElement.RequestBringIntoView from the content host). Similarly, you can request logical tree elements to be brought into view with the helper method LogicalTreeHelper.BringIntoView.

A ListBox implements a related but different method ScrollIntoView.
