WPF 回车转Tab实现跳转

1.重写窗体的KeyDown事件

    protected override void OnKeyDown(KeyEventArgs e)

    {

        if (e.Key == Key.Enter)

        {

            // MoveFocus takes a TraveralReqest as its argument.

            TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Next);

     

            // Gets the element with keyboard focus.

            UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

     

            // Change keyboard focus.

            if (elementWithFocus != null)

            {

                elementWithFocus.MoveFocus(request);

            }

            e.Handled = true;

        }

        base.OnKeyDown(e);

    }

 2.在基容器如Grid的KeyDown事件中

    private void Grid_KeyDown(object sender, KeyEventArgs e)

    {

        var uie = e.OriginalSource as UIElement;

        if (e.Key == Key.Enter)

        {

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

            e.Handled = true;

        }

    }
