How does VirtualQueryableCollectionView work exactly?

[Wizard6650]

I have been trying to use a VirtualQueryableCollectionView with a RadGridView but no matter what I do, the grid view is always empty.

// Person is an entity.
public class Person
{
    public string Name { get; set; }
    public string Dept { get; set; }
    public double Salary { get; set; }
}

public VirtualQueryableCollectionView PeopleView { get; set; }

// dbContext is an OData DataServiceContext. peopleQuery has a Count() of 1000 items.
IQueryable<Person> peopleQuery = dbContext.Person.OrderBy(x => x.Name);
PeopleView = new VirtualQueryableCollectionView(peopleQuery) { LoadSize = 50 };    
OnPropertyChanged(nameof(PeopleView));

<telerik:RadGridView AutoGenerateColumns="True"
                     ItemsSource="{Binding PeopleView}" />

But the grid view is empty. Just wondering what I'm doing wrong. Thank you.
