>How to force up/down arrows to move between rows ?

First of all, you'd have to have your own DataGridView class. Then, override the ProcessCmdKey method and handle the Up/Down arrows that way.

public class BBGridView : System.Windows.Forms.DataGridView
{
	protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
	{
		const int WM_KEYDOWN = 0x100;
		const int WM_SYSKEYDOWN = 0x104;

		if ((msg.Msg == WM_KEYDOWN) || (msg.Msg == WM_SYSKEYDOWN))
		{
			switch (keyData)
			{
				case Keys.Down:
					if (this.CurrentCell is DataGridViewComboBoxCell)
					{
						this.CurrentCell = this.Rows[this.CurrentCell.RowIndex + 1].Cells[this.CurrentCell.ColumnIndex];
						return true;
					}
					break;

				case Keys.Up:
					if (this.CurrentCell is DataGridViewComboBoxCell)
					{
						this.CurrentCell = this.Rows[this.CurrentCell.RowIndex - 1].Cells[this.CurrentCell.ColumnIndex];
						return true;
					}
					break;
			}
		}

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