示例1: OnPredictFocus
private void OnPredictFocus(object sender, RoutedEventArgs e)
{
DependencyObject predictionElement = null;
UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;
if (elementWithFocus != null)
{
// Only these four directions are currently supported
// by PredictFocus, so we need to filter on these only.
if ((_focusMoveValue == FocusNavigationDirection.Up) ||
(_focusMoveValue == FocusNavigationDirection.Down) ||
(_focusMoveValue == FocusNavigationDirection.Left) ||
(_focusMoveValue == FocusNavigationDirection.Right))
{
// Get the element which would receive focus if focus were changed.
predictionElement = elementWithFocus.PredictFocus(_focusMoveValue);
Control controlElement = predictionElement as Control;
// If a ContentElement.
if (controlElement != null)
{
controlElement.Foreground = Brushes.DarkBlue;
controlElement.FontSize += 10;
