I know this is a late answer, but maybe people searching can find this helpful, I it found on msdn in the "Navigating Focus Programmatically" section close to the bottom of the page:

Here's what I did

这就是我做的

protected override void OnPreviewLostKeyboardFocus(KeyboardFocusChangedEventArgs e)
{
    lostFocusControl = e.OldFocus;
}

private void PauseButton_PreviewKeyDown(object sender, KeyEventArgs e)
{
    // invoke OnPreviewLostKeyboardFocus handler
}
