xaml - Windows 手机 : no trigger in xaml?

Question

我不知道如何在Windows Phone 8的xaml中使用触发器。

但我看到有些人这样做，如下所示:

<toolkit:ListPicker Header="Background"
                                ExpansionMode="FullscreenOnly"
                                Template="{StaticResource ListPickerControlTemplate}"
                                VerticalAlignment="Top"
                                ItemsSource="{Binding Path=Buildings.ObjectList}"
                                Margin="0"
                                x:Name="buldings"
                                Padding="0">
                <i:Interaction.Triggers>
                    <i:EventTrigger EventName="SelectionChanged">
                        <i:InvokeCommandAction  Command="{Binding Path=BuildingSelectionCommand}"
                                                CommandParameter="{Binding Path=SelectedItem, ElementName=buldings}" />
                    </i:EventTrigger>
                </i:Interaction.Triggers>

但我没有 System.Windows.Interactivity。 而且我没能通过Nuget找到兼容的包。

感谢您的耐心等待。

Right click on References -> Add Reference.. -> Extensions -> Select System.Windows.Interactivity

程序集位于此处:
