WPF的DataTrigger使用

<Grid>
        <StackPanel HorizontalAlignment="Center"
                    VerticalAlignment="Center">
            <CheckBox Name="TestCheckBox"
                      Content="TestDataTriggerDemo"/>
            <TextBlock>
                <TextBlock.Style>
                    <Style TargetType="TextBlock">
                        <Setter Property="Text" Value="Hello,这是测试！"/>
                        <Setter Property="FontSize" Value="36"/>
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=TestCheckBox,Path=IsChecked}" Value="True">
                                <Setter Property="Text" Value="Hi，你好！数据触发器成功！"/>
                                <Setter Property="Foreground" Value="Blue"/>

                        </Style.Triggers>
