How to binding items colletion into Listbox with C++?

Question

Hi MSFT,

I encounter a problem to binding a items collection to listbox with C++.

I could binding a single object to listbox itemtemplate, just like following:

            Vector<String^>^ collection = ref new Vector<String^>;

            collection->Append("test name");

           listBox->ItemsSource = collection.

But i could not binding items collection into listbox, just like following:

          Item^ item = ref new Item;//item is created by myself.

         item->title = "test title";

         item->name = "name";           

          Vector<Item^>^ collection = ref new Vector<Item^>;

         listBoxt->ItemsSource = collection;

Maybe there is a special definition for Item managed class.

Please give me some help for this.

Thanks,

Kevin.
