Get value added properties from content in contentpresenter

I created a custom window with a template defined in the resource dictionary. There is no title bar in the window.

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:dsControls="clr-namespace:Something">
<Style x:Key="WindowRegionStyle"
       TargetType="Window">
    /** Other setters **/
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ContentControl">
                <Grid>
                    <Border Background="{StaticResource WindowBackground}"
                            BorderBrush="{StaticResource BorderBrushColor}"
                            BorderThickness="1"
                            CornerRadius="8"
                            HorizontalAlignment="Center"
                            VerticalAlignment="Center">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition Width="*" />
                            </Grid.ColumnDefinitions>
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto" />
                                <RowDefinition Height="Auto" />
                            </Grid.RowDefinitions>

                            <Border CornerRadius="8,8,0,0"
                                    BorderBrush="{StaticResource BorderBrushColor}"
                                    Background="{StaticResource HeaderColor}"
                                    Grid.ColumnSpan="2"
                                    Grid.Row="0">
                                <Label Content="{Binding Path=(dsControls:WindowDetails.Title), RelativeSource={RelativeSource TemplatedParent}}"
                                       FontSize="20" />
                            </Border>

                            <ContentPresenter Grid.Row="1" Grid.ColumnSpan="2" Content="{TemplateBinding Content}" />

                        </Grid>
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Content added to this template is equal UserControl. It all works.

But now I want to define the title in UserControl. To set the title, I created a attached property 'WindowDetails.Title' .

public static class WindowDetails
{
    public static string GetTitle(DependencyObject obj)
    {
        return (string)obj.GetValue(TitleProperty);
    }

    public static void SetTitle(DependencyObject obj, string value)
    {
        obj.SetValue(TitleProperty, value);
    }

    // Using a DependencyProperty as the backing store for Title.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty TitleProperty =
        DependencyProperty.RegisterAttached("Title", typeof(string), typeof(WindowDetails), new PropertyMetadata(""));

}

And I set the title to UserControlas follows:

<UserControl x:Class="Something.View"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:dsControls="clr-namespace:Something"
             Width="400"
             dsControls:WindowDetails.Title="Test">

      /** Some content **/
</UserControl>

Problem

I cannot associate a property value with a label in mine template.

What I already tried (and did wrong)

<Label Content="{Binding Path=(dsControls:WindowDetails.Title), RelativeSource={RelativeSource TemplatedParent}}"
                                       FontSize="20" />

and

<Label Content="{Binding Path=(dsControls:WindowDetails.Title), RelativeSource={RelativeSource Self}}"
                                       FontSize="20" />

Also by changing OwnerType attached property:

  • In WindowDetails

    public static readonly DependencyProperty TitleProperty =       DependencyProperty.RegisterAttached( "Title", typeof (string), typeof (WindowDetails), PropertyMetadata (""));

, . label property value.

  • UserControl

    public static readonly DependencyProperty TitleProperty =       DependencyProperty.RegisterAttached( "Title", typeof (string), typeof (UserControl), PropertyMetadata (""));

, , label .

attached property my UserControl label ?
