Returns the display string of the specified item in the value list
                virtual size_t GetListText( size_t index );  | 
            
The zero-based index of the item whose value is to be returned.
Returns a string containing the text to be displayed in the drop-down list.
The standard behavior is to return the value, followed by " - " and then the description,
      e.g. Value1 - Description of Value1.
        To change the behavior, derive a class from CXlWizExUIListProvider, 
        and override this virtual method.
