How to display row numbers in a ListView?

If you have a dynamic list where items are added, deleted or moved, you can still use this very nice solution and simply let the currentview of your listview refresh itself after the changements in your source list are done. This code sample removes the current item directly in the data source list "mySourceList" (which is in my case an ObservableCollection) and finally updates the line numbers to correct values .

ICollectionView cv = CollectionViewSource.GetDefaultView(listviewNames.ItemsSource);
if (listviewNames.Items.CurrentItem != null)
{
    mySourceList.RemoveAt(cv.CurrentPosition);
    cv.Refresh();
}
