dataGridView和textBox焦点问题

Question

form里有2个控件 1个dataGridView1 1个textBox1分别添加         private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData!=Keys.Up || e.KeyData!=Keys.Down )
            {
                textBox1.Select();
            } 
        }
        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData==Keys.Up || e.KeyData==Keys.Down )
            {
                dataGridView1.Select();
            } 
        }这是让两个控件根据键盘 来获得焦点 当dataGridView1获得焦点后 按↑↓键 dataGridView1总迟钝1排改怎样解决 请教老师们 呵呵把这两个事件合到 form1_KeyDown()里就没反应!!     private void form1_KeyDown(object sender, KeyEventArgs e)
{
                 if (e.KeyData!=Keys.Up || e.KeyData!=Keys.Down )
            {
                textBox1.Select();
            } 
            else
{
  dataGridView1.Select();
}
}

Answer 1

迟钝1排是什么意思..
如果在窗体键盘里使用加个 this.KeyPreview = true;

Answer 2

        private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData!=Keys.Up || e.KeyData!=Keys.Down )
            {
                textBox1.Focus();
            } 
        }
        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData==Keys.Up || e.KeyData==Keys.Down )
            {
                dataGridView1.Focus();
            } 
        }

Answer 3

dataGridView1_KeyDown事件没用
textBox1_KeyDown事件改成  if (e.KeyData == Keys.Up || e.KeyData == Keys.Down)
            {
                dataGridView1.Select();
                SendKeys.Send("{" + e.KeyData.ToString() + "}");
            }

Answer 4

执行事件使得 按2次↓键 dataGridView1跳到下一Row

Answer 5

用dataGridView1_KeyUp试试，我的就是这样解决的了
