[MonoDevelop] Force ComboBoxEntry DropDownList to show programatically

[Aaron Radich]

Thanks for the suggestion.  I couldn't get it to work, though, as I've
got 1 million search values and therefore I only want to populate the
Completion on the fly, with just the list store values that match what
the user typed into the Entry.  The EntryCompletion appears to need to
be populated before the user starts typing into the Entry.  So, I'm back
to wanting to use the ComboBox.  I've got it working 95%, would just
like to force the DropDown to display once it's populated.
