Hi,
I have a RadTreeListView (version 2011.2.712.35) whose ItemsSource is a custom implementation of INotifyCollectionChanged. The custom version is intended to be more efficient than ObservableCollection by bundling multiple sequential Adds or Removes into a single NotifyCollectionChanged event. The single event has a list of NewItems or OldItems with more than one item in it.
The RadTreeListView seems unable to handle this event correctly. In response to an Add event with two items, it only updates the display with the first of the items. In response to an Add event with 5 items, only the first two appear in the display.
Is this a known problem? Has it been fixed in a later version than the one I have?
Thanks,
Bob
