Implementing INotifyPropertyChanged in a C# Observable Collection - Changes Not Notifying UI
I'm refactoring my project and I tried several approaches but none seem to work. I'm working on a WPF application where I'm using an `ObservableCollection<T>` to bind to a `ListView`. However, I am encountering an issue where changes to the properties of the objects within the collection do not trigger UI updates. I have implemented `INotifyPropertyChanged` in my data model, but the UI remains unresponsive to changes. Here’s a snippet of my code: ```csharp public class MyModel : INotifyPropertyChanged { private string _name; public string Name { get => _name; set { if (_name != value) { _name = value; OnPropertyChanged(nameof(Name)); } } } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } } public class MyViewModel { public ObservableCollection<MyModel> Items { get; set; } public MyViewModel() { Items = new ObservableCollection<MyModel>(); // Add some initial items Items.Add(new MyModel { Name = "Item 1" }); } } ``` In my XAML, I'm binding the `ListView` like this: ```xml <ListView ItemsSource="{Binding Items}"> <ListView.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"/> </DataTemplate> </ListView.ItemTemplate> </ListView> ``` I've checked that the `DataContext` for the `ListView` is set correctly to an instance of `MyViewModel`. The collection updates correctly, but when I modify the `Name` property of an object in the collection like this: ```csharp Items[0].Name = "Updated Item"; ``` The UI does not reflect this change. I have verified that the `PropertyChanged` event is being triggered by placing breakpoints inside `OnPropertyChanged`, yet the UI remains unchanged. Are there any specific pitfalls or missed configurations when working with `ObservableCollection<T>` and `INotifyPropertyChanged` in WPF that could lead to this behavior? Any advice would be greatly appreciated! Any help would be greatly appreciated! I'd be grateful for any help.
