combobox keypress reject all keys

Question

I have a combobox and I want to use the keypress event (or keydown if I'm doing it wrong) and I'm using this code:

private void CbQuantitySoldSD_KeyPress(object sender, KeyPressEventArgs e)

 {

            e.Handled = false;

 }

to make it so that when you try and type nothing happens, but when I type into the combobox it still appears in the box. Any ideas?
