winrt-xaml – 禁用时更改Button的样式(IsEnabled = False)

<StackPanel>

    <Button x:Name="button" Content="Click Me" 
            IsEnabled="{Binding Ischecked,ElementName=checkBox}">
        <Interactivity:Interaction.behaviors>

            <Core:DatatriggerBehavior Binding="{Binding IsEnabled,ElementName=button,Mode=OneWay}" Value="True">
                <Core:ChangePropertyAction PropertyName="Opacity" Value="1"/>
            </Core:DatatriggerBehavior>

            <Core:DatatriggerBehavior Binding="{Binding IsEnabled,Mode=OneWay}" Value="false">
                <Core:ChangePropertyAction PropertyName="Opacity" Value=".5"/>
            </Core:DatatriggerBehavior>

        </Interactivity:Interaction.behaviors>
    </Button>

    <checkBox x:Name="checkBox" Ischecked="True" />

</StackPanel>

不要忘记您需要引用Behaviors SDK.

祝你好运！
