Question

I’m binding a table to a ObservableCollection,

ObservableCollection<MyObject> Items { get; protected set; }

but the table doesn’t seem to update (understandably so) when I change the properties one of the items in the collection. How to notify the ObservableCollection that I have changed one of the items’ property?

MyObject item = Items.FirstOrDefault(obj => obj.Entity.ID == x);
item.Description = something; //what should I do so that the view will be updated accordingly?

Answer 1

The type of the item instances in the ObservableCollection will need to implement INotifyPropertyChanged. For example, if you have an ObservableCollection<MyObject>, then MyObject will need to implement INotifyPropertyChanged.
