Remarks

Only a single UI element at a time can have focus.

A control can lose focus when another control gets focus, the application view changes, the user switches applications, or the user interacts with the system such that the application is no longer in the foreground.

Properties

Cancel

Gets or sets whether focus navigation should be canceled.
CorrelationId

Gets the unique ID generated when a focus movement event is initiated.
Direction

Gets the direction that focus moved from element to element within the app UI.
FocusState

Gets the input mode through which an element obtained focus.
Handled

Gets or sets a value that marks the routed event as handled. A true value for Handled prevents most handlers along the event route from handling the same event again.
InputDevice

Gets the input device type from which input events are received.
NewFocusedElement

Gets the most recent focused object.
OldFocusedElement

Gets the last focused object.
OriginalSource

Gets a reference to the object that raised the event. This is often a template part of a control rather than an element that was declared in your app UI.

(Inherited from RoutedEventArgs)

Methods

TryCancel()

Attempts to cancel the ongoing focus action.
TrySetNewFocusedElement(DependencyObject)

Attempts to redirect focus from the targeted element to the specified element.
