Raises the DropDown event.
The DropDown event occurs when the drop-down calendar is shown.
The OnDropDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors: When overriding OnDropDown in a derived class, be sure to call the base class's OnDropDown method so that registered delegates receive the event.
