Methods

	Name	Description
	BuildList	This is a convenience function to easily build lookuplist content from given resultset. Supports hierarchy, too. Note that for each Dictionary in the list, Value should have non-empty and unique value.
	CreateNewCTObject	Creates new lookuplist. Custom lists are always hierarchical. (Overrides CTObjectDataHandlerE, O, SCreateNewCTObject(String))
	DeleteObject	Deletes the given lookuplist from CT Database (Overrides CTObjectDataHandlerE, O, SDeleteObject(O))
	GetAllFromCTAPI	Queries all CTLookupList from CT API. (Overrides CTObjectDataHandlerE, O, SGetAllFromCTAPI)
	GetExtenionData	Gets extension data from lookuplist (Overrides CTObjectDataHandlerE, O, SGetExtenionData(O))
	HandleOnCustomListUpdate	Handler for CT API Event OnCustomListUpdate.
	Hook	Hook to events that query lookuplist data (Overrides EventExtensionHook(CTInterface))
	QueryAndUpdateLookupListContent	Call this to immediately update the lookuplist.
	QueryData	Perform the query against whatever API needed, and return the resultset. For each Dictionary in the list, Value should have non-empty and unique value. Hierarchical lists are build by having ParentValue that matches some other Dictionary's Value.
	RenameObject	Renames the given lookuplist in CT database with given name. The name must be unique! (Overrides CTObjectDataHandlerE, O, SRenameObject(O, String))
	SetExtensionData	Sets extension data to lookuplist (Overrides CTObjectDataHandlerE, O, SSetExtensionData(O, Byte))
	UnHook	Unhook from all events. (Overrides EventExtensionUnHook(CTInterface))
