Виртуализация TileLayoutControl

Question

Здравствуйте, я пишу приложение для WPF и у меня есть несколько динамических плиток (если честно, более 1000), и я пытаюсь реализовать виртуализацию, но независимо от того, что я пробовал, время загрузки этой страницы не снижается. Как я могу реализовать виртуализацию для этого кода?

<dxlc:TileLayoutControl ScrollBars="None" ItemsSource="{Binding Customers, NotifyOnSourceUpdated=True}" AllowItemMoving="False">
        <dxlc:TileLayoutControl.Resources>
            <Style TargetType="dxlc:Tile">
                <Setter Property="Width" Value="380" />
                <Setter Property="Header" Value="{Binding}" />
                <Setter Property="FontWeight" Value="Bold"/>
                <Setter Property="FontSize" Value="16"/>

                <Setter Property="dxwuin:Navigation.NavigationParameter" Value="{Binding clmnsn}" />
                <Setter Property="HeaderTemplate">
