WP下按下回车（enter）跳转下一个控件 上代码：

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);
        }

在窗体里写上就可以了。

 

WindowsForm下的按下回车（Enter）跳转到下一个控件
