Yes, if you create your business objects in a business object library or a web project (rather than a web site), you will have the ability to use the component designer for the business object class. Any property you set within the component designer is used by all business objects of that class (unless overwritten on a specific instance). To view the component designer, you can double-click the business object within the solution explorer or right-click it and select View Designer.There are also certain properties, such as ParentRelationship, that can only be set at design-time through the component designer.
