How can I send a single Downkey key when my user taps the numpad Enter key?

Question

This is purely for a usability request my clients have asked me.

They work with a datagridview typing in grades for students. So they pretty much go into zombie mode and start tapping in numbers, and they've told me that it would be easier if they could tap the numpad enter key to have the next vertical select focused.

Here's what I've tried to use:

private void dataGridView1_KeyUp(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        SendKeys.Send("{DOWN}");
    }
}

Unfortunately, it doesn't work as expected. Sometimes it seems to fire that key many times, causing the focus to scroll 2 or 3 or 4 cells downwards and really shaking up the users focus.

How can I make this work and make my clients happy?

private void datagridView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        bindingsource.MoveNext();
    }
}
