我正在尝试重新模拟Silverlight3进度条，在 ProgressBarIndicator 中的TextBlock中显示“Value”，并在 ProgressBarTrack
我认为在 Value 和 Maximum 属性上使用TemplateBinding会执行此操作，但它无法正常工作。
仅供参考我到目前为止的模板是：
<Style x:Key="ProgressBarStyle1" TargetType="ProgressBar">
<Setter Property="Foreground" Value="#FF027DB8"/>
<Setter Property="Background" Value="#FFD2D5D8"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Maximum" Value="100"/>
<Setter Property="Value" Value="50"/>
<Setter Property="IsTabStop" Value="False"/>
<Setter Property="BorderBrush">
<Setter.Value>
<LinearGradientBrush EndPoint=".5,1" StartPoint=".5,0">
<GradientStop Color="#FFAEB7BF" Offset="0"/>
<GradientStop Color="#FF919EA7" Offset="0.35"/>
<GradientStop Color="#FF7A8A99" Offset="0.35"/>
<GradientStop Color="#FF647480" Offset="1"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ProgressBar">
<Grid x:Name="Root">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Determinate"/>
<VisualState x:Name="Indeterminate">
<Storyboard RepeatBehavior="Forever">
<ObjectAnimationUsingKeyFrames Duration="00:00:00" Storyboard.TargetName="IndeterminateRoot" Storyboard.TargetProperty="(UIElement.Visibility)">
<DiscreteObjectKeyFrame KeyTime="00:00:00">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<ObjectAnimationUsingKeyFrames Duration="00:00:00" Storyboard.TargetName="DeterminateRoot" Storyboard.TargetProperty="(UIElement.Visibility)">
<DiscreteObjectKeyFrame KeyTime="00:00:00">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="ProgressBarTrack" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3" ToolTipService.ToolTip="{TemplateBinding Maximum}">
<Border.Effect>
<DropShadowEffect Color="#FF626262" Opacity="0.8"/>
</Border.Effect>
<TextBlock HorizontalAlignment="Right" VerticalAlignment="Center" Text="{TemplateBinding Maximum}" TextWrapping="NoWrap" Foreground="White" Margin="0,0,2,0"/>
</Border>
<Grid x:Name="ProgressBarRootGrid">
<Rectangle x:Name="ProgressBarRootGradient" RadiusX="1.5" RadiusY="1.5" Margin="{TemplateBinding BorderThickness}" Canvas.ZIndex="1" Stroke="Black">
<Rectangle.Fill>
<LinearGradientBrush EndPoint=".7,1" StartPoint=".7,0">
<GradientStop Color="#B2FFFFFF" Offset="0"/>
<GradientStop Color="#0CFFFFFF" Offset="0.198"/>
<GradientStop Color="#91FFFFFF" Offset="0.336"/>
<GradientStop Color="#0CFFFFFF" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<Grid x:Name="IndeterminateRoot" Visibility="Collapsed">
<Rectangle x:Name="IndeterminateSolidFill" Fill="{TemplateBinding Foreground}" Stroke="#FF448DCA" StrokeThickness="0" RadiusX="2" RadiusY="2" Margin="{TemplateBinding BorderThickness}" Opacity="1" RenderTransformOrigin="0.5,0.5"/>
</Grid>
<Grid x:Name="DeterminateRoot" Margin="1">
<Grid x:Name="ProgressBarIndicator" Margin="0" HorizontalAlignment="Left" ToolTipService.ToolTip="{TemplateBinding Value}">
<Rectangle x:Name="ProgressBarIndicator1" Fill="{TemplateBinding Foreground}" StrokeThickness="0" RadiusX="1.5" RadiusY="1.5" Margin="0"/>
<TextBlock HorizontalAlignment="Right" Margin="0,0,2,0" VerticalAlignment="Center" TextWrapping="Wrap" Foreground="White" Text="{TemplateBinding Value}"/>
</Grid>
</Grid>
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我通过本地UserControl.Resources引用它，如下所示：
<ProgressBar x:Name="availableHoursProgress"
Margin="2"
Foreground="#FF42B802"
Background="Red"
Style="{StaticResource ProgressBarStyle1}"
BorderThickness="0"
BorderBrush="{x:Null}"
Value="2"
Maximum="7.5"
HorizontalAlignment="Stretch"
/>
提前感谢您提供的任何帮助，

====更新====
好的，这个问题是因为我绑定的对象类型为 Double ，而 Textblock.Text 期望字符串。
所以我的新问题是如何将转换器应用于TemplateBinding，或者在ProgressBar上公开字符串属性：
public string ValueString{ get { return Value.ToString(); } }
