Nested ContentControls with template - wpf

Question

I have a custom WindowStyle, the XAML looks like this:
<Style TargetType="{x:Type Window}"
x:Key="WindowStyle">
/** Some setters **/
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<AdornerDecorator>
<Grid Background="#88000000"
x:Name="WindowBackgroundGrid">
<Border x:Name="WindowContentBorder"
Background="{DynamicResource WindowBackground}"MaxHeight="{Binding Source={x:Static SystemParameters.FullPrimaryScreenHeight}}"
MaxWidth="{Binding Source={x:Static SystemParameters.FullPrimaryScreenWidth}}"
Margin="20">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<!-- Header -->
<Border BorderBrush="{DynamicResource BorderBrushColor}"
Background="{DynamicResource PaneHeader_Background}"
Grid.Row="0">
<TextBlock Text="Title"Foreground="{DynamicResource DefaultForeground}"
FontSize="16"
FontWeight="Bold"
Margin="5,5,2,5" />
</Border>
<!-- Content -->
<ScrollViewer Grid.Row="1"
Margin="5">
<ContentPresenter Content="{TemplateBinding Content}" />
</ScrollViewer>
</Grid>
</Border>
</Grid>
</AdornerDecorator>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now I want the inner Grid in a seperate Style so that I can use it elsewhere.
<Style x:Key="WindowContentStyle"
TargetType="{x:Type ContentPresenter}">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<!-- Header -->
/** Border control **/
<!-- Content -->
<ScrollViewer Grid.Row="1"
Margin="5">
<ContentPresenter Content="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}" />
</ScrollViewer>
</Grid>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
And I use a ContenPresenter in my WindowStyle to present it:
<ContentPresenter>
<ContentPresenter.Style>
<Style TargetType="{x:Type ContentPresenter}"
BasedOn="{StaticResource WindowContentStyle}" />
</ContentPresenter.Style>
</ContentPresenter>
Problem
The edit above didn't give me any errors, but it doesn't present my WindowContentStyle.
When I set the Content property of the Window control and load the style
this.window.Content = view;
this.window.Style = (Style)Application.Current.TryFindResource("WindowStyle");
the content is shown in the ContentPresenter in the WindowStyle and not in WindowContentStyle. Because of this, the Template is not used and I don't have a header with a title.
How can I make my outer ContentPresenter pass on the Content to my inner ContentPresenter (the one in WindowContentStyle)?
Thanks in advance!

You should use a ContentControl to display your content, not a ContentPresenter. From the ContentPresenter Class page on MSDN:
You typically use the ContentPresenter in the ControlTemplate of a ContentControl to specify where the content is to be added.
From the ContentControl Class page on MSDN:
A ContentControl has a limited default style. If you want to enhance the appearance of the control, you can create a new DataTemplate.
