Gets or sets the maximum number of objects retrieved by the collection from a data store.
An integer that specifies the maximum number of objects that will be retrieved by the collection from a data store. 0 indicates that all objects which match the criteria will be retrieved.
If this property's value is greater than 0, then the collection retrieves only the first TopReturnedObjects objects which match the collection's XPBaseCollection.Criteria.
Use the TopReturnedObjects property to adjust an XPCollection's object retrieval options before it's loaded. Once a collection is loaded, changing this property has no effect. To make the changes take effect, you need to manually reload the collection. When an XPCollection is created using a constructor with the criteriaEvaluationBehavior parameter, it is loaded immediately. So, changing the TopReturnedObjects property will also have no effect.
