AdaptiveTrigger是否可以在DataTemplate中工作？

这是我用来自定义我的ShellNavigation的代码,除了视觉状态之外它工作得很好.它们不会触发任何东西.

<shell:ShellHeadView x:Key="ShellHeadView_01">
    <shell:ShellHeadView.ContentTemplate>
        <DataTemplate>
            <Grid Margin="20,0">
                <VisualStateManager.VisualStateGroups>
                    <VisualStateGroup>
                        <VisualState x:Name="GreenBackgroundVisualState">
                            <VisualState.Setters>
                                <Setter Target="headViewLeft.Background" Value="Green" />
                            </VisualState.Setters>
                            <VisualState.StateTriggers>
                                <AdaptiveTrigger MinWindowWidth="1000"/>
                            </VisualState.StateTriggers>
                        </VisualState>
                        <VisualState x:Name="OrangeBackgroundVisualState">
                            <VisualState.Setters>
                                <Setter Target="headViewLeft.Background" Value="Orange" />
                            </VisualState.Setters>
                            <VisualState.StateTriggers>
                                <AdaptiveTrigger MinWindowWidth="2000"/>
                            </VisualState.StateTriggers>
                        </VisualState>
                        <VisualState x:Name="RedBackgroundVisualState">
                            <VisualState.Setters>
                                <Setter Target="headViewLeft.Background" Value="Red" />
                            </VisualState.Setters>
                            <VisualState.StateTriggers>
                                <AdaptiveTrigger MinWindowWidth="3000"/>
                            </VisualState.StateTriggers>
                        </VisualState>
                    </VisualStateGroup>
                </VisualStateManager.VisualStateGroups>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
                <Grid Grid.Column="0" x:Name="headViewLeft" Width="100" Height="90">

                </Grid>
