    i have a ItemSource of an ObservableCollection<ITestObject> and the user can add new rows to my RadGridView.

    If the collections contains one item, the GridView takes this type for adding a new one.
    In the case that the collection is empty, the user is unable to add one item.
    Is there a way to work with collection of interface objects? Or is there a workaround?
