c# - WP8: Change the Listboxitem Datatemplate on Selection Changed

I have a listbox in windows phone 8,

For that i want to change the datatemplate for the Selected Item.

I have done this is WPF like :

<Window.Resources>

        <DataTemplate x:Key="ItemTemplate">
            <TextBlock Text="{Binding}" Foreground="Red" />
        </DataTemplate>

        <DataTemplate x:Key="SelectedTemplate">
            <TextBlock Text="{Binding}" Foreground="Green" />
        </DataTemplate>

        <Style TargetType="{x:Type ListBoxItem}" x:Key="ContainerStyle">
            <Setter Property="ContentTemplate" Value="{StaticResource ItemTemplate}" />
            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="ContentTemplate" Value="{StaticResource SelectedTemplate}" />
                </Trigger>
            </Style.Triggers>
        </Style>

    </Window.Resources>
    <ListBox x:Name="lstItems" ItemContainerStyle="{StaticResource ContainerStyle}" />

But i don't know how to achieve this in Windows Phone 8 because it doesn't

in C# you can easily use

ListBox.ItemTemplate = (DataTemplate)this.Resources["yourkeytemplate"];

dont forget to declare your template in resource XAML
