计时器延时执行下，要不确实存在这个问题，blur后就没搞了

    private void dgv1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
    {
        int max = 5;
        if (e.ColumnIndex == 0 && dgv1.CurrentCell.Value != null && dgv1.CurrentCell.Value.ToString().Length > max)
        {
            MessageBox.Show("姓名最大长度为:" + max + "个字符，请重新输入！");
            DataGridViewCell cur = dgv1.CurrentCell;


            System.Timers.Timer t = new System.Timers.Timer(10);
            t.Elapsed += delegate(object tsender, System.Timers.ElapsedEventArgs te)
            {
                this.Invoke(new SetCur(() =>
                {
                    dgv1.CurrentCell = cur;
                    dgv1.BeginEdit(true);
                    t.Enabled = false;
                    t.Close();
                }));

            };
            t.Enabled = true;
        }
    }
