How to get the focused control in WPF?

问题:

How can I get a current focused control in WPF?

I found some solution for WinForms, but invoking WIN32 API function, didn't work in WPF?

Is there any way for doing it in WPF?

回答1:

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:

UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

Here's what I did

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

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