1.1 基本 Trigger

 

 

<Window.Resources>
        <Style TargetType="{x:Type CheckBox}">
            <Style.Triggers>
                <Trigger Property="IsChecked" Value="true">
                    <Setter Property="Foreground" Value="Orange"></Setter>
                    <Setter Property="FontSize" Value="10"></Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Window.Resources>
    <StackPanel>
        <CheckBox Content="----------------------"></CheckBox>
        <CheckBox Content="++++++++++++++++++++++"></CheckBox>
        <CheckBox Content="======================"></CheckBox>
        <CheckBox Content="______________________"></CheckBox>
    </StackPanel>

1.2 MultiTrigger 

多条件同时满足才会触发

 

 

<Window.Resources>
        <Style TargetType="{x:Type CheckBox}">
            <Style.Triggers>
                <MultiTrigger>
                    <MultiTrigger.Conditions>
                        <Condition Property="IsChecked" Value="true"></Condition>
                        <Condition Property="Content" Value="小桥流水人家"></Condition>
                    </MultiTrigger.Conditions>
                    <MultiTrigger.Setters>
                        <Setter Property="FontSize" Value="15"></Setter>
                        <Setter Property="Foreground" Value="Red"></Setter>
                    </MultiTrigger.Setters>
                </MultiTrigger>
            </Style.Triggers>
        </Style>
    </Window.Resources>
    <StackPanel>
        <CheckBox Content="枯藤老树昏鸦"></CheckBox>
        <CheckBox Content="小桥流水人家"></CheckBox>
        <CheckBox Content="古道西风瘦马"></CheckBox>
        <CheckBox Content="断肠人在天涯"></CheckBox>
    </StackPanel>
