   ByVal entityProperty As DataEntityProperty _
) As UniqueId

'Usage
 
Dim instance As EntityManager
Dim entity As Object

value = instance.GenerateId(entity, entityProperty)

public UniqueId GenerateId( 
   object entity,
   DataEntityProperty entityProperty
)

entity: The Entity object for which the new ID will be generated
entityProperty: The EntityProperty in which the new ID will be set

Exceptions

Exception	Description
System.ArgumentException	Incorrect entity type/property
IdeaBlade.Core.IdeaBladeException	IdGenerator not found

Remarks

You must implement the IIdGenerator interface to use ID generation. See the DevForce Developer's Guide for more information on custom ID generation.

If you are using a SQL Server Identity property you do not need to call GenerateId for the property.
