I'm using RadDataForm for the first time and to mr it seems there's an uncommon behavior. I've bound MyRadDataForm.ItemsSource to a property called 'UserList' which is of type 'ObservableCollection<UserViewModel>'. When I load users from database and add them to the ObservableCollection, then UI/RadDataForm gets updated via INotifiyPropertyChanged.
Now I want to refresh the displayed data so I clear the collection (UserList.Clear()), get the users from database again and then re-add those users to the collection (UserList.AddRange(usersFromDatabase). The problem is my UI doesn't get updated anymore. It seems that RadDataForm is only updating one time.
