You can handle the KeyDown event, and prevent the key press to be forwarded to the control.

private void Form1_Load( object sender, EventArgs e )
winComboBox1.TextBoxArea.KeyDown += new KeyEventHandler( TextBoxArea_KeyDown );

void TextBoxArea_KeyDown( object sender, KeyEventArgs e )
if( e.KeyCode == Keys.Down || e.KeyCode == Keys.Up )
e.SuppressKeyPress = true;
