把Enter键转换为Tab键总结

在这里需要在输入的时候，按下enter键自动转向下一个tab对应的控件，下面总结了几种实现的方法：

 

方法一

        private void Form1_Load(object sender, EventArgs e)
        {
            this.KeyPreview = true;
        }

 

        private void Form1_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Right || e.KeyCode == Keys.Down)
            {
                if (ActiveControl != null)
                {
                    this.SelectNextControl(this.ActiveControl, true, true, true, false);
                }
            }
            else if (e.KeyCode == Keys.Left || e.KeyCode == Keys.Up)
            {
                if (ActiveControl != null)
                {
                    this.SelectNextControl(this.ActiveControl, false, true, true, false);
                }
            }
        }

方法二

        private void Form1_Load(object sender, EventArgs e)
        {
            this.KeyPreview = true;
        }

 

        private void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == '/r')
            {
                System.Windows.Forms.SendKeys.Send("/t");
                e.Handled = true;
            }
        }

 

方法三

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            if (keyData == Keys.Enter)
            {
                if (!(ActiveControl is Button))
                {
                    System.Windows.Forms.SendKeys.Send("{tab}");
                    return true;
                }
            }
            if (keyData == Keys.F1)
            {
                MessageBox.Show("Just Test___" + keyData.ToString());
            }

 

            return base.ProcessCmdKey(ref msg, keyData);
        }

 

说明，上面的方法一虽然实现了enter键转换为tab键的功能，但是，它对所有的控件，都将enter转换为tab了，所以如果想达到当焦点到达login按钮就停止然后执行对应的事件，建议采用后面两种方法。
