 | ObservableFilteredCollectionT | Initializes a new instance of the ObservableFilteredCollectionT class. |
Properties| Name | Description | |
|---|---|---|
 | Items |
Returns the collection that the ReadOnlyObservableCollectionAdapterT, TList wraps.

 | Finalize | (Overrides ObjectFinalize) |
| OnCollectionChanged |
Raises the CollectionChanged event.
(Inherited from ReadOnlyObservableCollectionAdapterT, TList) |
| OnPropertyChanged |
Raises the PropertyChanged event.

Events| Name | Description | |
|---|---|---|
 | CollectionChanged |
Occurs when the collection changes.

Remarks
Changes in the source collection will be tracked always, changes in the individual objects that would affect the filter will be tracked when any of the live tracking properties changes.
The order of the elements may be different than the order in the source collection; also changes that affect the items order in the source collection (see Move, Insert(Int32, Object)) will be ignored.
This collection does not hold a reference to the source collection. To keep the source collection alive, the object generating the ObservableFilteredCollectionT must hold a reference to the source collection.
