Juan,
Does something like this work?

private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
	MessageBox.Show(e.KeyChar.ToString());
	if (e.KeyChar == (char) System.Windows.Forms.Keys.Enter)
	{
		MessageBox.Show("Enter");
	}
	else
	{
		MessageBox.Show("Not Enter");
	}
}

I tested it on a standard textbox.

>>>Thank's Einar, the problem is that the textbox of the datagrid column doesn't catch the keyup event.
