Initializes a new instance of the XPCollection class with specified settings.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v21.1.dll


public XPCollection(
    PersistentCriteriaEvaluationBehavior criteriaEvaluationBehavior,
    Session session,
    XPClassInfo objType,
    CriteriaOperator condition


Name Type Description
criteriaEvaluationBehavior PersistentCriteriaEvaluationBehavior

A PersistentCriteriaEvaluationBehavior enumeration value that specifies how the persistent criteria are evaluated.

session Session

The Session that will be used to load and save persistent objects.

objType XPClassInfo

The persistent class metadata information of objects to include into the collection.

condition CriteriaOperator

The CriteriaOperator that specifies the criteria for object selection.


Note that when an XPCollection is created using a constructor with the criteriaEvaluationBehavior parameter, the collection is loaded immediately and its XPBaseCollection.LoadingEnabled property is automatically set to false. After that, the collection cannot be reloaded using the XPBaseCollection.Reload method, since object loading is disabled.
