您可以在Xaml中使用它,如下所示：

<ItemsControl ItemsSource="{Binding TextList}" HorizontalAlignment="Center">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Grid Background="Red">
                <interactivity:Interaction.Behaviors>
                    <local:SlideMechanicBehavior />
                </interactivity:Interaction.Behaviors>
                <TextBlock FontSize="22" Text="{Binding }" />
            </Grid>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

不要忘记在项目中添加Behaviors SDK>添加参考>扩展对话框.
