If the data operation methods (ObjectDataSource.SelectMethod, ObjectDataSource.UpdateMethod, ObjectDataSource.DeleteMethod, and ObjectDataSource.InsertMethod) are instance methods, an instance of the business object is created before the method is executed. You can prevent the business object from being created for each call by saving the object in the ObjectDataSourceDisposingEventArgs.ObjectInstance property in the ObjectDataSource.ObjectDisposing event handler. In subsequent ObjectDataSource.ObjectCreating events, you can retrieve the business object from the ObjectDataSourceEventArgs.ObjectInstance property.
