Class ListView<T>
Provides a scrollable list of data where each item can be activated to perform an action,
with a strongly-typed Value property that returns the selected object of type
T from the underlying ObservableCollection<T>.
public class ListView<T> : ListView, IDisposable, ISupportInitializeNotification, ISupportInitialize, IDesignable, IValue<int?>, IValue<T>, IValueType Parameters
TThe type of items in the collection.
- Inheritance

IValue<T>
- Inherited Members
- Extension Methods
Remarks
ListView<T> extends ListView by implementing
IValue<TValue>. The Value property returns the currently selected
object of type T rather than the selected index.
All ListView functionality (rendering, marking, keyboard navigation, key and mouse bindings) is inherited unchanged. Use SetSource(ObservableCollection<T>?) to provide the typed source collection.
The base Value (index-based, IValue<TValue> with
T = int?) remains accessible by casting to ListView or
IValue<int?>.
Constructors
- ListView()
Initializes a new instance of ListView<T>.
