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

To Trigger OnChange in ObservableCollection List

1. Get index of selected Item
2. Remove the item from the Parent
3. Add the item at same index in parent

Example:

int index = NotificationDetails.IndexOf(notificationDetails);
NotificationDetails.Remove(notificationDetails);
NotificationDetails.Insert(index, notificationDetails);
