推荐答案

这是您的操作方法.

<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, 
                ElementName=button, Mode=OneWay}" Value="False">
                <Core:ChangePropertyAction PropertyName="Opacity" Value=".5"/>
            </Core:DataTriggerBehavior>

        </Interactivity:Interaction.Behaviors>
