TileLayoutControl虚拟化

Question

你好我正在写一个WPF应用程序，我有一些动态Tiles（说实话，超过1000），我正在尝试实现虚拟化，但无论我尝试加载这个页面的时间不要下去。如何为此代码实现虚拟化？

<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="Background" Value="DarkGray" />
                <Setter Property="Foreground" Value="Black" />
                <Setter Property="dxwuin:Navigation.NavigateTo" Value="CustomerDetailsView" />
                <Setter Property="dxwuin:Navigation.NavigationParameter" Value="{Binding clmnsn}" />
                <Setter Property="HeaderTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">

                                        <TextBlock FontWeight="Normal" FontSize="12" Foreground="Black" VerticalAlignment="Center" Text="{Binding clmnafm}"/>
