ObservableCollection ReorderThemeTransition

Question

Is ObservableCollection compatible with ReorderThemeTransition in the RTM version of Windows 8?  I am having a heck of a time getting ReorderThemeTransition to ever work inside a GridView whether bound directly to an ObservableCollection or CollectionViewSource.  Any help regarding how to get the UI to animation the new 'order' of a collection would be greatly appreciated.

Answer 1

Please post some code so I can test this scenario.

If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Answer 2

Bind to an ObservableCollection and use ObservableCollection.Move to move an item to a new index in the collection.  The UI is updated to reflect the new index, but no transition runs, it just draws at the new position.

Answer 3

Okay.  I'll look into doing it some other way.

Answer 4

This isn't a supported scenario.
