ListBox

I was curious if I should use a listbox or combobox to look up warehouse part numbers and then fire an event if it is clicked. I want to be able to click that number and then send a specific command out a serial port. I currently use a selection of hyperlinks to do this but there are now to many and a dropdown list would be helpful to select from and fire the same command as if it was the hyperlink.

Here is my code for when a hyperlink is clicked for part HC1_101... could I replace this with a listbox to send the same command? Can I just add the links to the dropdown list?

private void linkLabel_HC1_101_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    if (serialPort1.IsOpen)
    {
        var content = new List<byte>();
        content.Add(2);
        content.AddRange(Encoding.ASCII.GetBytes("01P00101##"));
        content.Add(3);
        byte[] buffer = content.ToArray();
        serialPort1.Write(buffer, 0, buffer.Length);
    }
}
