ObservableCollection not noticing when Item in it changes (even with INotifyPropertyChanged)

Question

Does anyone know why this code doesn\'t work:

public class CollectionViewModel : ViewModelBase {  
    public ObservableCollection Con         


        

Answer 1

Instead of an ObservableCollection or TrulyObservableCollection, consider using a BindingList and calling the ResetBindings method.

For example:

private BindingList _tfsFiles;

public BindingList TfsFiles
{
    get { return _tfsFiles; }
    set
    {
        _tfsFiles = value;
        NotifyPropertyChanged();
    }
}

Given an event, such as a click your code would look like this:

foreach (var file in TfsFiles)
{
    SelectedFile = file;
    file.Name = "Different Text";
    TfsFiles.ResetBindings();
}

My model looked like this:

namespace Models
{
    public class TfsFile 
    {
        public string ImagePath { get; set; }

        public string FullPath { get; set; }

        public string Name { get; set; }

        public string Text { get; set; }

    }
}
