WPF ListView Binding ItemsSource in XAML
If you don't do it already, in XAML for example, you need to set DataContext for your binding. Also since People property does not implement INotifyPropertyChanged you might want to create this list before InitializeComponent, at very least before you set DataContext, to be sure list is ready when binding is evaluated. You can add to your ObservableCollection later but if you create it after that point without notifying UI it won't work
public ListView(){ this.People = new ObservableCollection<Person>(); InitializeComponent(); this.DataContext = this; this.People.Add(new Person() { Name = "John Doe", Age = 42, Mail = "john@doe-family.com" }); this.People.Add(new Person() { Name = "Jane Doe", Age = 39, Mail = "jane@doe-family.com" }); this.People.Add(new Person() { Name = "Sammy Doe", Age = 7, Mail = "sammy.doe@gmail.com" }); }
Put this line after the existing code in xaml.cs
this.DataContext = People;and replace your xaml with
ItemsSource="{Binding People}" to
ItemsSource="{Binding}"
