WPF 中如何激发Tab键？

[qldsrx]

WPF用你当前焦点所在的FrameworkElement对象的MoveFocus方法：

FrameworkElement.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

[DENQH]

 private void Grid1_KeyDown(object sender, KeyEventArgs e)
        {
            FrameworkElement fsource = e.Source as FrameworkElement;
            if (e.Key == Key.Down || e.Key == Key.Enter)
            {                
                fsource.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next)) ;
            }
            if (e.Key == Key.Up)
            {
                fsource.MoveFocus(new TraversalRequest(FocusNavigationDirection.Previous));
            }
        }

这样可以但是如果到了ComboBox就会下不去了，如何解决？

[DENQH]

 private void Grid1_KeyUp(object sender, KeyEventArgs e)
        {
            UIElement element = Keyboard.FocusedElement as UIElement;
            if (e.Key == Key.Down || e.Key == Key.Enter)
            {                            
                if (element != null)
                {
                    element.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
                }
            }
            if (e.Key == Key.Up)
            {
                if (element != null)
                {
                    element.MoveFocus(new TraversalRequest(FocusNavigationDirection.Previous));
                }
            }
        }
