title: prevent dropdown area from opening of combobox control in windows forms
body: <p>I have a custom combo box control in windows forms. I want to achieve a functionality wherein based on some condition the dropdown area should not be displayed i.e. I need to prevent the combo box from opening based on some condition. </p>
  
  <p>I found a link where this can be achieved but it is completely preventing the dropdown area from showing. Also i am not able to tweak the method as per my convinience.
