EntityViewTEntity Class

EntityView provides 'view' capabilities for an entity collection. This class supports filtering and sorting in-memory, using type safe objects. Binding an entity collection to a grid or other complex databinding control will actually make the control bind to an instance of this class.

Properties
  NameDescription
Public propertyAllowEdit
Gets / sets whether you can update items in the list.
(Inherited from EntityViewBaseTEntity.)
Public propertyAllowNew
Gets/sets whether you can add items to the list using AddNew.
(Inherited from EntityViewBaseTEntity.)
Public propertyAllowRemove
Gets whether you can remove items from the list, using Remove(Object) or RemoveAt(Int32).
(Inherited from EntityViewBaseTEntity.)
Public propertyContainer
Gets the container for the component.
(Inherited from MarshalByValueComponent.)
Public propertyCount
Gets the number of elements contained in the ICollection.
(Inherited from EntityViewBaseTEntity.)
Public propertyDataChangeAction
Gets or sets the data change action which specifies what to do when the data in the related collection of an entity view changes. A change in data can be: entity added or changed. If an entity is removed from the underlying collection, the entity is simply removed from the entity view, as the view doesn't contain any data by itself.
(Inherited from EntityViewBaseTEntity.)
Public propertyDesignMode
Gets a value indicating whether the component is currently in design mode.
(Inherited from MarshalByValueComponent.)
Protected propertyEntityIndices
Gets the entity indices for the entities which are in this view, in the order sorted by the sorter set.
(Inherited from EntityViewBaseTEntity.)
Protected propertyEvents
Gets the list of event handlers that are attached to this component.
(Inherited from MarshalByValueComponent.)
Public propertyFilter
Gets or sets the filter to use for this entity view.
(Inherited from EntityViewBaseTEntity.)
Public propertyIsSorted
Gets whether the items in the list are sorted.
(Inherited from EntityViewBaseTEntity.)
Public propertyItem
Gets the element at the specified index in this view.
(Inherited from EntityViewBaseTEntity.)
Public propertyRaisesItemChangedEvents
Gets a value indicating whether the IRaiseItemChangedEvents object raises ListChanged events.
(Inherited from EntityViewBaseTEntity.)
Public propertyRelatedCollection
Gets the related collection set for this view.
Protected propertyRelatedCollectionInternal
Gets the related collection using a property which is solely for internal usage. This is then used by the derived classes to expose the collection in a more typed manner.
(Inherited from EntityViewBaseTEntity.)
Public propertySite
Gets or sets the site of the component.
(Inherited from MarshalByValueComponent.)
Public propertySortDirection
IBindingList member. Gets the direction of the sort. This property returns the value of the first SortClause in the set sorter.

Public propertySorter
Gets or sets the sorter for this entity view. Setting this property will re-sort the view and will reset the view in databinding scenario's.
