|
Name | Description | |
---|---|---|
ActiveContext |
Gets / sets the active context this entity collection is in. Setting this property is not adding the entity collection to the context,
it will make contained entities be added to the passed in context. If the entity collection is already in a context, setting this property has
no effect. Setting this property is done by framework code, use the Context's Add/Get methods to work with contexts and entity collections.
(Inherited from CollectionCoreT.) | |
AllowEdit |
Default: true. If set to false, entities inside this collection won't be editable in a complex databinding scenario.
(Inherited from CollectionCoreT.) | |
AllowNew |
Default: true. If set to false, no new entities will be added through databinding.
(Inherited from CollectionCoreT.) | |
AllowRemove |
Default: false. If set to true, entities can be removed through databinding.
(Inherited from CollectionCoreT.) | |
Capacity |
Gets / sets the initial capacity of the entity collection.
(Inherited from CollectionCoreT.) | |
ConcurrencyPredicateFactoryToUse |
Gets / sets the IConcurrencyPredicateFactory instance to use when creating entity objects during a GetMulti() call or when AddNew is called.
(Inherited from CollectionCoreT.) | |
ContainingEntity |
Gets the entity which contains this collection (e.g. Customer, if this collection is the Customer's Orders collection), or null if this
collection isn't part of any entity.
| |
ContainingEntityMappedField |
Gets the name of the field mapped onto the relation in the opposite entity which is represented by this collection, if this collection is
contained by an entity. E.g. it will return "Customer" if the relation Customer - Order has the field 'Customer' mapped onto it in Order and
this collection is the Orders collection in Customer. If this collection isn't contained in any entity, an empty string is returned.
(Inherited from CollectionCoreT.) | |
ContainsDirtyContents |
Returns true if this collection contains dirty objects. If this collection contains dirty objects, an
already filled collection should not be refreshed until a save is performed. This property is calculated in real time
and can be time consuming when the collection contains a lot of objects. Use this property only in cases when the value
of this property is used to do a refetch or not.
| |
ContainsListCollection |
Gets a value indicating whether the collection is a collection of IList objects.
| |
Count |
Gets the number of elements contained in the ICollectionT.
(Inherited from CollectionCoreT.) | |
DefaultView |
Gets the default view for this entitycollection. The returned value is the same instance every time this property is read.
It's an entity view without a filter or a sorter.
| |
DeserializationInProgress |
Gets or sets a value indicating whether [deserialization in progress].
(Inherited from CollectionCoreT.) | |
DirtyEntities |
Returns a readonly collection of entities which are flagged as dirty.
This collection is determined on the fly, you can use this collection to remove dirty entities from this entity collection.
(Inherited from CollectionCoreT.) | |
DoNotPerformAddIfPresent |
When set to true, an entity passed to Add() or Insert() will be tested if it's already present. If so, the index is returned and the
object is not added again. If set to false (default) this check is not performed. Setting this property to true can slow down fetch logic.
(Inherited from CollectionCoreT.) | |
EntityFactoryToUse |
The EntityFactory2 to use when creating entity objects when bound to a grid and AddNew is enabled.
| |
EntityFactoryToUseInternal |
Gets or sets the entity factory to use
(Overrides CollectionCoreTEntityFactoryToUseInternal.) | |

Item |
Gets or sets the object at the specified index.
(Inherited from CollectionCoreT.) | |
Items |
Items contained by this collection. Returns simply this instance.
(Inherited from CollectionCoreT.) | |
RemovedEntitiesTracker |
Gets or sets the entity collection which should be used as removed entities tracker. If this property is set to an IEntityCollection2 instance,
all entities which are removed from this collection are marked for deletion and placed in this removed entities tracker collection.
This collection can then later on be used to delete these entities from the database in one go.
| |
RemovedEntitiesTrackerInternal |
