Binding ItemsSource to ObservableCollection more than once

[Johannes]

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.

Thanks for your reply. Can you show me a link to your bug tracking system or how will I know when this is fixed? I need the refreshable RadDataForm in my current project.

Hi,

You can track the progress of the issue in our Feedback portal here:
Changes on the ItemsSource Collection are not reflected in the UI.
