Remarks

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.

Properties

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)
TargetObject	Gets the object that should be made visible in response to the event.
TargetRect	Gets the rectangular region in the object's coordinate space which should be made visible.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
InvokeEventHandler(Delegate, Object)	Invokes event handlers in a type-specific way, which can increase event system efficiency.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
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)
ToString()	Returns a string that represents the current object. (Inherited from Object)
