Class TrulyObservableCollection<T>

This class extends the System.Collections.ObjectModel.ObservableCollection<T> for generic content types that implement System.ComponentModel.INotifyPropertyChanged and does send the System.Collections.ObjectModel.ObservableCollection<T>.CollectionChanged event also when an element of the collection changes. This is the intended behaviour of the System.Collections.ObjectModel.ObservableCollection<T> and documented as such in the MSDN, however, it does not work as intended.

Constructors

TrulyObservableCollection()

Will initialize with a hook to the System.Collections.ObjectModel.ObservableCollection<T>.CollectionChanged event and add or remove event listeners to the items in the collection.

Declaration

public TrulyObservableCollection()

TrulyObservableCollection(IEnumerable<T>)

Will initialize with a hook to the System.Collections.ObjectModel.ObservableCollection<T>.CollectionChanged event and add or remove event listeners to the items in the collection.

Declaration

public TrulyObservableCollection(IEnumerable<T> collection)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<T>	collection	The System.Collections.Generic.IEnumerable<T> from which to seed.

Methods

AddRange(IEnumerable<T>)

Adds the elements of the specified collection to the end of the System.Collections.ObjectModel.ObservableCollection<T>.

Declaration

public void AddRange(IEnumerable<T> collection)

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<T>	collection	The collection whose elements should be added to the end of the System.Collections.ObjectModel.ObservableCollection<T>. The collection itself cannot be null, but it can contain elements that are null, if type T is a reference type.

Exceptions

Type	Condition
System.ArgumentNullException	`collection` is null.

ClearItems()

This first removes all event subscriptions to 'PropertyChanged' on the 'Items' and then calls the base method.

Declaration

protected override void ClearItems()

Overrides

System.Collections.ObjectModel.ObservableCollection<T>.ClearItems()

InsertRange(Int32, IEnumerable<T>)

Inserts the elements of a collection into the System.Collections.ObjectModel.ObservableCollection<T> at the specified index.

Declaration

public void InsertRange(int index, IEnumerable<T> collection)

Parameters

Type	Name	Description
System.Int32	index	The zero-based index at which the new elements should be inserted.
System.Collections.Generic.IEnumerable<T>	collection	The collection whose elements should be inserted into the List<T>. The collection itself cannot be null, but it can contain elements that are null, if type T is a reference type.

Exceptions

Type	Condition
System.ArgumentNullException	`collection` is null.
System.ArgumentOutOfRangeException	`index` is not in the collection range.
