Syntax

public class ReadOnlyObservableCollection<T> : ReadOnlyCollection<T>, IList<T>, ICollection<T>, IList, ICollection, IReadOnlyList<T>, IReadOnlyCollection<T>, IEnumerable<T>, IEnumerable, INotifyCollectionChanged, INotifyPropertyChanged
Type Parameters
T

The type of elements in the collection.
Remarks

This class provides a read-only view of an observable collection while forwarding all change notifications from the underlying collection. It prevents modification while maintaining observability.

Constructors

ReadOnlyObservableCollection(ObservableCollection<T>)

Initializes a new instance of the ReadOnlyObservableCollection<T> class with the specified observable collection.

Declaration
public ReadOnlyObservableCollection(ObservableCollection<T> list)
Parameters
ObservableCollection<T> list

The ObservableCollection to wrap as read-only.

Methods

OnCollectionChanged(NotifyCollectionChangedEventArgs)

Fires the CollectionChanged event when the underlying collection changes.

Declaration
protected virtual void OnCollectionChanged(NotifyCollectionChangedEventArgs args)
Parameters
NotifyCollectionChangedEventArgs args

The event arguments describing the collection change.

OnPropertyChanged(PropertyChangedEventArgs)

Fires the PropertyChanged event when a property of the underlying collection changes.

Declaration
protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)
Parameters
System.ComponentModel.PropertyChangedEventArgs args

The event arguments describing the property change.

Events

CollectionChanged

Occurs when an item is added, removed, changed, moved, or the entire list is refreshed.

Declaration
protected event NotifyCollectionChangedEventHandler CollectionChanged
Event Type
NotifyCollectionChangedEventHandler

PropertyChanged

Occurs when when a property of an object changes change. Calling the event is developer's responsibility.

Declaration
protected event PropertyChangedEventHandler PropertyChanged
Event Type
System.ComponentModel.PropertyChangedEventHandler

Explicit Interface Implementations

INotifyCollectionChanged.CollectionChanged

Occurs when an item is added, removed, changed, moved, or the entire list is refreshed.

Declaration
event NotifyCollectionChangedEventHandler INotifyCollectionChanged.CollectionChanged
Returns
NotifyCollectionChangedEventHandler
