UWP ToggleButton图像取决于IsChecked

Question

我想给我的ToggleButton取决于不同的图像IsChecked的状态ToggleButton ，但在UWP风格触发不再存在，所以它以不同的方式来完成。

我遇到了讨论，其中假定的解决方案是使用DataTriggerBehavior ，但我无济于事。

我要实现的目标（未选中蓝色，选中绿色）：

以下内容是否朝着正确的方向发展？

<ToggleButton 
    x:Name="ToggleButton"
    IsChecked="{Binding SignalButtonSelected, Mode=TwoWay}"
    Command="{Binding SignalButtonCommand}">
    <Grid>
    <Image x:Name="IsCheckedImage" Source="Images/Buttons/Button signal.png">
        <Interactivity:Interaction.Behaviors>
            <Core:DataTriggerBehavior Binding="{Binding IsChecked, ElementName=ToggleButton}" Value="True">
                <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsCheckedImage}" PropertyName="Visibility" Value="Collapsed" />
            </Core:DataTriggerBehavior>
        </Interactivity:Interaction.Behaviors>
    </Image>
    <Image x:Name="IsUncheckedImage" Source="Images/Buttons/Button electric ns.png">
        <Interactivity:Interaction.Behaviors>
            <Core:DataTriggerBehavior Binding="{Binding IsChecked, ElementName=ToggleButton}" Value="False">
                <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsUncheckedImage}" PropertyName="Visibility" Value="Collapsed" />
            </Core:DataTriggerBehavior>
        </Interactivity:Interaction.Behaviors>
    </Image>
    </Grid>
</ToggleButton>

还是有更好/更轻松的方法来实现这一目标？ 我还阅读了一些有关VisualStateManager的知识，而我对这些知识也有零经验。

希望有人可以把我推向正确的方向...

尝试这个

<ToggleButton x:Name="ToggleButton"
                IsChecked="{Binding SignalButtonSelected, Mode=TwoWay}"
                Command="{Binding SignalButtonCommand}">
    <Grid>
        <Image x:Name="IsCheckedImage"
                Source="Images/Buttons/Button signal.png">
            <Interactivity:Interaction.Behaviors>
                <Core:DataTriggerBehavior Binding="{Binding IsChecked, ElementName=ToggleButton}"
                                            Value="True">
                    <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsCheckedImage}"
                                                PropertyName="Visibility"
                                                Value="Collapsed" />
                    <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsUncheckedImage}"
                                                PropertyName="Visibility"
                                                Value="Visible" />
                </Core:DataTriggerBehavior>
            </Interactivity:Interaction.Behaviors>
        </Image>
        <Image x:Name="IsUncheckedImage"
                Source="Images/Buttons/Button electric ns.png">
            <Interactivity:Interaction.Behaviors>
                <Core:DataTriggerBehavior Binding="{Binding IsChecked, ElementName=ToggleButton}"
                                            Value="False">
                    <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsCheckedImage}"
                                                PropertyName="Visibility"
                                                Value="Visible" />
                    <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsUncheckedImage}"
                                                PropertyName="Visibility"
                                                Value="Collapsed" />
                </Core:DataTriggerBehavior>
            </Interactivity:Interaction.Behaviors>
        </Image>
    </Grid>
</ToggleButton>
