How to Bind a List to DataGrid using MVVM at Runtime

All, I have an View model that is bound to a `DataGrid` using MVVM.

    <DataGrid ItemsSource="{Binding Path=Resources}">...</DataGrid>

Where

    public ObservableCollection<ResourceViewModel> Resources { get; private set; }

in the `ResourceViewModel` class I have the following properties

    public string ResourceName
    {
        get { return this.resource.ResourceName; }
        set {
            ...
        }
    }

    public ObservableCollection<string> ResourceStringList
    {
        get { return this.resource.ResourceStringList; }
        set {
            ...
        }
    }

All properties are displayed in the `DataGrid` but the `ResourceStringList` colletion is being displayed as '(Collection)'.

How can I get the `DataGrid` to display each of the strings contained in the `ResourceStringList` in its own column?

Thanks very much for your time.
