关于WPF后台触发键盘按键

1.变向响应Tab按键

private void Grid_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));

                }

            }

        }

 

2.响应键盘按键，根据需求响应不同key键

控件.RaiseEvent(new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, Key.Right)

{ RoutedEvent = UIElement.KeyDownEvent });
