Property Value
By default this gets the IGoIdentifiablePart.IGoIdentifiablePart.PartID, if the object is an IGoIdentifiablePart and the IGoIdentifiablePart.PartID is not -1. Otherwise this value is null, and you will probably want to set this to whatever value you are using in your application.
This is not the same as the "id" property for a DHTML element.
