SliderThumbStyle中的文本

所以这是我的 SliderThumbStyle Style :

<Style x:Key="SliderThumbStyle" TargetType="{x:Type Thumb}">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Thumb}">
                    <Grid>
                        <Border Name="outerBorder"
                                Background="{DynamicResource LabelDisableForegroundColor}"
                                BorderBrush="{DynamicResource LabelDisableForegroundColor}"
                                Height="20"
                                Width="20"
                                Opacity="1" 
                                BorderThickness="2"
                                CornerRadius="8"/>
                        <TextBlock x:Name="sliderValue"
                                   FontSize="11"
                                   Foreground="Silver"
                                   Text="{Binding }"
                                   VerticalAlignment="Center"
                                   HorizontalAlignment="Center"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

如你所见,我把 Thumb 简单的 TextBlock 为了看水流 Slider value

我需要在课文里放些什么 property 以下内容:

Text="{Binding }"
