【问题描述】：
我有一个忙碌的装饰器，如下所示
<controls:BusyDecorator x:Name="Busy" BusyStyle="{StaticResource busyStyle}" FadeTime="00:00:00.2" IsBusyIndicatorShowing="{Binding IsBusy}" Tag="Description">
还有风格
<Style x:Key="busyStyle" TargetType="{x:Type Control}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<ControlTemplate.Resources>
<Style TargetType="{x:Type Rectangle}">
<Setter Property="Width" Value="8" />
<Setter Property="Height" Value="16" />
<Setter Property="Stroke" Value="Black" />
<Setter Property="StrokeThickness" Value="1" />
<Setter Property="RadiusX" Value="2" />
<Setter Property="RadiusY" Value="2" />
<Setter Property="RenderTransformOrigin" Value=".5,.5" />
</Style>
</ControlTemplate.Resources>
<Canvas Width="64" Height="64">
<Rectangle Canvas.Left="24">
<Rectangle.Fill>
<SolidColorBrush x:Name="top" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Left="10" Canvas.Top="6">
<Rectangle.RenderTransform>
<RotateTransform Angle="-45" />
</Rectangle.RenderTransform>
<Rectangle.Fill>
<SolidColorBrush x:Name="topLeft" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Top="24" Width="16" Height="8">
<Rectangle.Fill>
<SolidColorBrush x:Name="left" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Left="10" Canvas.Top="34">
<Rectangle.RenderTransform>
<RotateTransform Angle="45" />
</Rectangle.RenderTransform>
<Rectangle.Fill>
<SolidColorBrush x:Name="bottomLeft" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Left="24" Canvas.Top="40">
<Rectangle.Fill>
<SolidColorBrush x:Name="bottom" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Left="38" Canvas.Top="34">
<Rectangle.RenderTransform>
<RotateTransform Angle="-45" />
</Rectangle.RenderTransform>
<Rectangle.Fill>
<SolidColorBrush x:Name="bottomRight" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Top="24" Canvas.Left="38" Width="16" Height="8">
<Rectangle.Fill>
<SolidColorBrush x:Name="right" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<Rectangle Canvas.Left="38" Canvas.Top="6">
<Rectangle.RenderTransform>
<RotateTransform Angle="45" />
</Rectangle.RenderTransform>
<Rectangle.Fill>
<SolidColorBrush x:Name="topRight" Color="#DFDFDF" />
</Rectangle.Fill>
</Rectangle>
<TextBlock Canvas.Left="1" Canvas.Top="64" FontSize="11" Foreground="White" Text="{TemplateBinding Tag}" />
</Canvas>
我想要的是能够在运行时将微调器上的文本设置为我喜欢的任何内容。现在我在 Tag 属性上将它硬编码为 POC，但我没有在微调器中显示任何文本。如果我改变了
{TemplateBinding Tag}
在样式的底部为一个普通的硬编码文本值，它显示文本。
如何从父控件传播文本字符串以显示在样式渲染上？
更新
我有一个类表示这个控件，如下
[StyleTypedProperty(Property = "BusyStyle", StyleTargetType = typeof (Control))]
public class BusyDecorator : Decorator
{
#region IsBusyIndicatorShowing Property
/// <summary>
/// Identifies the IsBusyIndicatorShowing dependency property.
/// </summary>
public static readonly DependencyProperty IsBusyIndicatorShowingProperty = DependencyProperty.Register(
"IsBusyIndicatorShowing",
typeof (bool),
typeof (BusyDecorator),
new FrameworkPropertyMetadata(false,
FrameworkPropertyMetadataOptions.AffectsMeasure,
OnIsShowingChanged));
/// <summary>
/// Gets or sets if the BusyIndicator is being shown.
/// </summary>
public bool IsBusyIndicatorShowing
{
get { return (bool) GetValue(IsBusyIndicatorShowingProperty); }
set { SetValue(IsBusyIndicatorShowingProperty, value); }
}
由于样式以 Control 类型为目标，因此我无法将模板绑定到我在 BusyDecorator 类型上创建的依赖项属性。如果我将样式的 TargetType 更改为“BusyDecorator”，它会说找不到模板属性？
