WPF overriding setter properties

I'm using a style in my XAML for a label:

<Style x:Key="TreatEye" TargetType="Label">
        <Setter Property="Foreground" Value="#d1d1d1" />
        <Setter Property="FontWeight" Value="Bold" />
        <Setter Property="FontSize" Value="30" /开发者_如何学C>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Label">
                    <Canvas>                            
                        <TextBlock x:Name="retreatText" Canvas.Left="80" Canvas.Top="5" FontSize="16"  Text="Retreatment"/>                                                        
                        <TextBlock x:Name="bioinsulatorText" Canvas.Left="21" Canvas.Top="33" Text="Bioinsulator" />
                        <TextBlock x:Name="kxlText" Canvas.Left="21" Canvas.Top="70" Text="KXL Kit" />
                    </Canvas>
...

The problem I'm seeing is that the FontSize property of "reatreatText" is not overridden from the setter value of 30. This builds fine, but the end display has "reatreatText" as size 30. Why is this value not overridden?

Thanks in advance.

Sorry, but I tried your code inside Kaxaml and works as expected:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Page.Resources>
  <Style x:Key="TreatEye" TargetType="Label">
        <Setter Property="Foreground" Value="#d1d1d1" />
        <Setter Property="FontWeight" Value="Bold" />
        <Setter Property="FontSize" Value="30" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Label">
                    <Canvas>                            
                        <TextBlock x:Name="retreatText" Canvas.Left="80" Canvas.Top="5" FontSize="16" Text="Retreatment"/>                                                        
                        <TextBlock x:Name="bioinsulatorText" Canvas.Left="21" Canvas.Top="33" Text="Bioinsulator" />
                        <TextBlock x:Name="kxlText" Canvas.Left="21" Canvas.Top="70" Text="KXL Kit" />
                    </Canvas>
                </ControlTemplate>
        </Setter.Value>                
      </Setter>
     </Style>
    </Page.Resources>

  <Grid>  
    <Label Style="{StaticResource TreatEye}">Ejemplo</Label>
  </Grid>
</Page>

Result:

You need to set a TemplateBinding on the TextBlock.

<TextBlock x:Name="retreatText"
           Canvas.Left="80" 
           Canvas.Top="5" 
           FontSize="{TemplateBinding FontSize}" 
           Text="Retreatment"/> 

That's how the setter properties get propogated to the internal structure.
