UWP切换按钮图像取决于已检查

win-universal-app uwp xaml c#

bas · 技术社区 · 7 年前

ToggleButton 不同的图像取决于 IsChecked 切换按钮 ,但在UWP中,触发器不再存在,因此必须以不同的方式进行。

DataTriggerBehavior

我想要实现的目标(蓝色未选中,绿色已选中):

<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>

希望有人能把我推向正确的方向。。。

试试这个

<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>

                    <Core:ChangePropertyAction TargetObject="{Binding ElementName=IsUncheckedImage}"
                                                PropertyName="Visibility"
