Methods
Name | Description | |
---|---|---|

Returns an instance of ICollectionViewFactory that can be used as a
source of a CollectionViewSource.

Used for views with anonymous type constructor as the result selector,
converts the View to a View<dynamic> so it can be used for data binding and programmatic access.

Properties
Name | Description | |
---|---|---|
Count |
Gets the total number of elements in the view. (Inherited from View.) |
|
CurrentItem |
Gets the current item in the view.
(Inherited from View.) |
|
DeferredMaintenance |
This property overrides DeferredMaintenance. (Overrides View..::..DeferredMaintenance.) |
|
IsReadOnly |
Gets a value indicating whether this view is read-only, not updatable. (Inherited from View.) |
|
Item |
Gets the view item (element) at the specified ordinal position. (Inherited from View<(Of <(<'T>)>)>.) |
|
Key |
Gets the key value of the group.
|
|
MaintenanceMode |
This property overrides MaintenanceMode. (Overrides View..::..MaintenanceMode.) |
|
MoveToFirstOnReset |
Gets or sets a value indicating that the first item must be made current after initial loading or reset
(on any Reset notification) if current item was not set by other means. The default is True.
(Inherited from View.) |
|
Order |
Gets a value indicating whether and how this view preserves item order if it exists in its base data source. (Inherited from View.) |
|

Gets the collection of ViewRow objects used for programmatic access to view elements (items) and for data binding. (Inherited from View.) |
|
Transaction |
Gets an instance of ITransaction associated with the view.

every time the view is updated, so the programmer does not need to do it manually in code.
(Inherited from View.) |
Events
Name | Description | |
---|---|---|
Changed |
Occurs after an item of the view or the entire view has changed.
