IBindableObservableVector IBindableObservableVector IBindableObservableVector IBindableObservableVector Interface


Extends IBindableVector by adding a VectorChanged event for change notification.

struct winrt::Windows::UI::Xaml::Interop::IBindableObservableVector : IBindableIterable, IBindableVector
public interface IBindableObservableVector : IEnumerable, IList
Public Interface IBindableObservableVector Implements IEnumerable, IList

This interface supports the creation of data bindable collections in C++. When programming with .NET, you should use ObservableCollection(Of T) or implement IList and INotifyCollectionChanged. For more info, see Binding to collections.

Interface inheritance

IBindableObservableVector inherits IBindableVector and IBindableIterable. Types that implement IBindableObservableVector also implement the interface members of IBindableVector and IBindableIterable for C++ usage, or IList and IEnumerable for Microsoft .NET usage.


VectorChanged VectorChanged VectorChanged VectorChanged

Occurs when the vector collection changes (add, delete, item change).


Append(Object) Append(Object) Append(Object) Append(Object)

Appends an item to the end of the vector.

First First First First

Returns a bindable iterator that iterates over the items in the collection.

(Inherited from IBindableIterable)
GetAt(UInt32) GetAt(UInt32) GetAt(UInt32) GetAt(UInt32)

Returns the item at the specified index in the vector.
