    Is there a way to programmatic way to cause a RadListView to refresh itself? 

    When I navigate back to a page with a RadListView, I need the page to update. I tried overriding OnAppearing to trigger the update.

    I have a ObservableCollection<T> in a VM class that inherits from NotifyPropertyChangedBase, and I call OnPropertyChanged on the VM. Even though the data in the ObservableCollection has changed, I can't get the ListView to update.

    Any hints?

    Hello Gerry,

    If the ItemsSource of the RadListView is bound in TwoWay mode and the underlying collection is ObservableCollection our component should be automatically updated whenever the collection changes. Could you please share some implementation details? How exactly the RadListView is defined on your page and how is your collection updated? 

    We are looking forward to hearing from you.
