Firstly, I tried a generic list but the data-bound ListBox on the view did not update when I added or removed items in the viewmodel. I then tried GridViewDataSet with a grid, still to no avail.

When I populate the list/GridViewDataSet with initial values then items are shown in the view.

Is there an ObservableCollection?

Can you show your ViewModel and DotHTML markup? – Dusan Janosik Jan 17 '18 at 22:36
Is there a sample that shows how to add/remove items in a list dynamically using a button initiated command handler – Mofolo Jan 19 '18 at 08:07
It should work with `List`, there is no need for the observable collection. How is your list declared? Is there both `{ get; set; }`? Are you using the `Bind` attribute? – Tomáš Herceg Jan 19 '18 at 17:47
Sorry for the delayed reply. Yes, it does work. – Mofolo Jan 25 '18 at 13:52
