    <CollectionView ItemsSource="{Binding Items}">
        <CollectionView.ItemTemplate>
            <DataTemplate>
                <ContentView>
                    <ContentView.Triggers>
                        <DataTrigger TargetType="ContentView" Binding="{Binding .}" Value="Second">
                            <Setter Property="Background" Value="Purple"/>
                        </DataTrigger>
                    </ContentView.Triggers>
                    <Label Text="{Binding .}" FontSize="24" Background="Azure" />
                </ContentView>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>

The color of the items should be Azure and the selected Purple, but they are all Azure.

If I remove the Background on the element, then all are white with one being Purple as I expected.

The label background will cover the content view background... Oops.
