messages or log files if you are hitting an issue that looks similar to
this resolved bug and you do not yet see a matching new report.
In order to replace ObservableCollection<MyObject> for the ItemSource property of a ListView, your collection implements INotifyCollectionChanged interface. This exposes the CollectionChanged event.
When adding an item to my collection, I fire my CollectionChanged event, but of course, only if there are subscribers on the event. In this case, CollectionChanged event is still null after being set as the source for the listview ItemSource.
My guess is somehow the connection is expecting specific container types and not a type of INotifyCollectionChanged? (probably because there's no IEnumerable access from the interface)?
Mike, can you please supply a ziped reduced reproduction of the issue you are encountering along with the actual behavior (null ref exception?) and expected behavior?
Assigned to you as you were last to requeste info for this bug.
Because we have not received a reply to our request for more information we are closing this issue. If you are still encountering this issue, please reopen the ticket with the requested information. Thanks!
