Parameters

request
Type: System.Windows.InputTraversalRequest

The direction that focus is to be moved, as a value of the enumeration.

Return Value

Type: SystemBoolean
Returns true if focus is moved successfully; false if the target element in direction as specified does not exist or could not be keyboard focused.
Remarks

This implementation overrides UIElementMoveFocus and seals the method.

Examples

The following example implements a handler that handles several possible button inputs. Each button represents a possible FocusNavigationDirection. The handler tracks the element with current keyboard focus, and calls MoveFocus on that element, by specifying the appropriate FocusNavigationDirection as initialization for the TraversalRequest type parameter provided.

			' Creating a FocusNavigationDirection object and setting it to a
			' local field that contains the direction selected.
			Dim focusDirection As FocusNavigationDirection = _focusMoveValue

			' MoveFocus takes a TraveralReqest as its argument.
			Dim request As New TraversalRequest(focusDirection)

			' Gets the element with keyboard focus.
			Dim elementWithFocus As UIElement = TryCast(Keyboard.FocusedElement, UIElement)

			' Change keyboard focus.
			If elementWithFocus IsNot Nothing Then
				elementWithFocus.MoveFocus(request)
			End If
// Creating a FocusNavigationDirection object and setting it to a 
// local field that contains the direction selected.
FocusNavigationDirection focusDirection = _focusMoveValue;

// MoveFocus takes a TraveralReqest as its argument.
TraversalRequest request = new TraversalRequest(focusDirection);

// Gets the element with keyboard focus.
UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

// Change keyboard focus. 
if (elementWithFocus != null)
{
    elementWithFocus.MoveFocus(request);
}
