C# Класс Habanero.BO.BusinessObjectLookupList

Provides a lookup-list sourced from business object collections. A lookup-list is typically used to populate features like a ComboBox, where the string would be displayed, but the Guid would be the value stored (for reasons of data integrity). The string-Guid pair collection will be created using each object's ToString() function and the object's Guid ID.
NB: this class does not provide criteria, so the entire collection will be loaded.

BusinessObjectLookupList ( string assemblyName, string className, string criteria, string sort, int timeout ) : System

Constructor to initialise a new lookup-list
CreateDisplayValueDictionary ( IBusinessObjectCollection col, bool sortByDisplayValue ) : string>.Dictionary

Returns a collection of string Guid pairs from the business object collection provided. Each pair consists of a string version of a business object and the object's ID.
CreateDisplayValueDictionary ( IBusinessObjectCollection col, bool sortByDisplayValue, ConvertPrimaryKeyGetAsValueToString coverter ) : string>.Dictionary

Returns a collection of string Guid pairs from the business object collection provided. Each pair consists of a string version of a business object and the object's ID.
GetBusinessObjectCollection ( ) : IBusinessObjectCollection

Returns a collection of related business objects for a particular property based on the definition of the business object lookup list. This returns the same set of data as returned by the GetLookupList() method.
GetIDValueLookupList ( ) : string>.Dictionary

Returns the lookup list contents being held where the list is keyed on the list key either a Guid, int or Business object i.e. the value being stored for the property. The display value can be looked up.
GetLookupList ( ) : string>.Dictionary

Returns a lookup-list for all the business objects stored under the class definition held in this instance
GetLookupList ( IDatabaseConnection connection ) : string>.Dictionary

Returns a lookup-list for all the business objects stored under the class definition held in this instance, using the database connection provided
GetLookupList ( bool ignoreTimeout ) : string>.Dictionary

Returns a lookup-list for all the business objects stored under the class definition held in this instance. An option is included to ignore the default timeout, which causes use of a cached version within the timeout period.
