Updating datasource data doesn't update filtered view

I follow the MVVM documents and inherited BindableBase in Order class.
Use SetProperty in the Hidden field. Now I can update the Grid when value change.
I have another question. In the MVVM documentation. It have example to use ObservableCollection<T>
If I use ObserverableCollection<Order> as the binding source, when I update one of item in the collection, do the grid receive update notification? I tried it doesn't. Don't know if I miss sth.
Btw. In the document https://documentation.devexpress.com/#WindowsForms/CustomDocument113956, the SetProperty have typo , it throw compile error
set { SetProperty(ref titleValue, "Title");}
It should be :
set { SetProperty(ref titleValue, value, "Title");}

Hello Jason,
The ObservableCollection class does not implement the IBindingList interface. So, the grid can't get notifications about its changes. I suggest that you use BindingList  instead. This way, the Grid should be updated correctly.
Attached is a small sample that demonstrates this approach.

Btw. In the document  https://documentation.devexpress.com/#WindowsForms/CustomDocument113956, the SetProperty have typo , it throw compile error
Thanks for pointing out this error. I created a separate thread on your behalf: Documentation - Correct the mistake in the Data Bindings and Notifications article. We will update that thread as soon as we correct our documentation.
