Equivalent WinUI property: Microsoft.UI.Xaml.Controls.ItemsControl.ItemsSource.
public:
property Platform::Object ^ ItemsSource { Platform::Object ^ get(); void set(Platform::Object ^ value); };
IInspectable ItemsSource();
void ItemsSource(IInspectable value);
public object ItemsSource { get; set; }
var object = itemsControl.itemsSource;
itemsControl.itemsSource = object;
Public Property ItemsSource As Object
<itemsControl ItemsSource="bindingDeclaration"/>
-or-
<itemsControl ItemsSource="resourceReferenceToSource"/>
Property Value
The object that is used to generate the content of the ItemsControl. The default is null
.
Remarks
The type of the object that you set the ItemsSource property to must implement one of these interfaces.
.NET | C++/WinRT | C++/CX |
---|---|---|
IEnumerable<Object> | IVector<IInspectable> | IIterable<IInspectable> |
IEnumerable | IBindableObservableVector | IBindableIterable |
The ItemsControl can provide better performance if the ItemsSource property value also implements a random-access list interface.
The ItemsControl can raise collection-changed notification events if the ItemsSource property value also implements a collection-changed notification interface.
.NET | C++/WinRT | C++/CX |
---|---|---|
INotifyCollectionChanged | IObservableVector<IInspectable> | IObservableVector<IInspectable> |
For .NET, in order for the collection-changed events to be handled, the ItemsSource property must also implement the non-generic IList interface.
