Yes, in effect, you must use code and call OpenDropDown() ( or set DroppedDown to true ) to open the dropdown. The reason for this design is that it allows you to manage your dropdown state (closed, shown ) from any event handler (mouse down, click, etc. ). It provides better control, and allows you to modify your dropdown control before it is displayed – quite useful.
I hope this helps.
