+ * 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.
