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

 /// <summary>        /// 方法一：实现按下回车跳到下一个控件（不论是什么控件，如果需要可以在里面加上对控件类型的判断）        /// </summary>        /// <param name="e"></param>        protected override void OnKeyDown(KeyEventArgs e)        {            if (e.KeyCode == Keys.Enter)            {                int i = 0;                foreach (Control c in this.Controls)                {                    if (c.Focused)                    {                        i = c.TabIndex;                        break;                    }                }                foreach (Control c in this.Controls)                {                    if (c.TabIndex == (i + 1))                    {                        c.Focus();                        break;                    }                }            }        }        /// <summary>        /// 方法二：灵活方便，可以通过方法中的参数控制是否要进入控件的子控件中，是否忽略tobstop的设置。        /// </summary>        /// <param name="e"></param>        protected override void OnKeyPress(KeyPressEventArgs e)        {            //base.OnKeyPress(e);            if (e.KeyChar == (char)13)            {                e.Handled = true;                this.SelectNextControl(this.ActiveControl, true, true, true, false);            }        }        /// <summary>        /// 方法三：直接将enter按键转化为tab按键        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void Form1_KeyDown(object sender, KeyEventArgs e)        {            MessageBox.Show("");            if (e.KeyCode == Keys.Enter)            {                SendKeys.Send("{TAB}");                e.Handled = true;            }        }
