title: How to hide list of combobox whose DropDownStyle is set to simple?
body: <p>I need to have drop down style of ComboBox set to simple because I have to hide the arrow that shows when style is set to ComboBox or DropDownList, this ComboBox will be disabled. I need to bind some items to this ComboBox via binding source, but the value is selected based on some properties calculated on a press of some button, that is why I need it disabled and without the arrow.

  With this, because item is automatically selected, I need to hide the list that shows below. Is it possible to hide the list and how?</p>
