回答1:

use ObserableListCollection

and

yourGridviewOrListview1.ItemsSource = null;
yourGridviewOrListview1.ItemsSource = SingletonClass.YourObList;

To update the GridView if entries in your list are added, removed or moved you should use an ObservableCollection instead of a List.

To update GridView entries if properties of the list entries change the class of your list entries needs to implement INotifyPropertyChanged and also use databinding in the templates the GridView uses to display your list entries.
