This class suppoprts imple cases where a UI control can
be directly synchronized with a data property.
Such controls are: the different text controls
(synchronizing the "Text" , "Value", "Date", "Time" property),
Checkbox controls, Dropdown listbox controls (synchronizing the
SelectedItems[] property.
For those controls, static convenience methods are offered, to simplify use.
