WPF TabControl Templates + ItemContainerStyle - wpf

Question

I am attempting to create a Tab Control Style that basically looks like buttons at the top that are centered and content panel below that displays the tabitem content.
I have am kind of new to templates but what I have so far works very well except one thing. I want to be able to set the default forground color for text elements. Normally I have accomplished this by using the ContentPresenter with dependency elements. So something like this.
<ContentPresenter TextElement.Foreground="White"/>
This basically makes any TextElement Control written by this Presenter to inherit this property.
Now I am trying to do the same thing but it's not working! I believe it has something to do with my style being wrong.
Style:
<Style x:Key="MainMenuTab" TargetType="{x:Type TabControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabControl}">
<Grid KeyboardNavigation.TabNavigation="Local" Width="{TemplateBinding Width}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!-- Tab Headers Panel -->
<Grid Grid.Row="0" Background="{StaticResource Brush_ApplicationTabBackground}">
<TabPanel
Name="HeaderPanel"
Grid.Row="0"
Panel.ZIndex="1"
HorizontalAlignment="Center"
VerticalAlignment="Center"
IsItemsHost="True"
KeyboardNavigation.TabIndex="1"
Background="{StaticResource Brush_ApplicationTabBackground}"
>
</TabPanel>
</Grid>
<!-- Tab Body -->
<Border
Name="Border"
Grid.Row="1"
Background="{StaticResource Brush_ApplicationBackground}"
BorderBrush="Transparent"
BorderThickness="1"
CornerRadius="2"
KeyboardNavigation.TabNavigation="Local"
KeyboardNavigation.DirectionalNavigation="Contained"
KeyboardNavigation.TabIndex="2" >
<ContentPresenter
Name="PART_SelectedContentHost"
Margin="4"
ContentSource="SelectedContent" />
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<!-- Each Tab should look like this -->
<Setter Property="ItemContainerStyle">
<Setter.Value>
<Style>
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid Background="{StaticResource Brush_ApplicationTabBackground}">
<Border Width="50" x:Name="BorderTab" Height="50" Margin="5" BorderThickness="1" ClipToBounds="True" BorderBrush="Transparent" Background="Transparent" CornerRadius="5">
<Rectangle x:Name="BackgroundRec" Fill="Transparent" Stroke="Transparent" Width="50" Height="50" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<ContentPresenter Name="TheHeaderContentPresenter" Width="50" Height="50" Margin="5" ContentSource="Header" HorizontalAlignment="Center" VerticalAlignment="Center" TextElement.Foreground="White"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.Setters>
<Setter TargetName="BorderTab" Property="BorderBrush" Value="{StaticResource Brush_ApplicationTabHighlight}"/>
<Setter TargetName="BorderTab" Property="BorderThickness" Value="3"/>
<Setter TargetName="BackgroundRec" Property="Fill" Value="{StaticResource Brush_ApplicationTabHighlight}"/>
<Setter Property="Panel.ZIndex" Value="1"/>
</Trigger.Setters>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Trigger.Setters>
<Setter TargetName="BorderTab" Property="BorderBrush" Value="{StaticResource Brush_ApplicationTabBackground}"/>
<Setter TargetName="BorderTab" Property="BorderThickness" Value="0"/>
<Setter TargetName="BackgroundRec" Property="Fill" Value="{StaticResource Brush_ApplicationTabBackground}"/>
</Trigger.Setters>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
In my ContentPresenter under ItemContainerStyle has the TextElement.Foreground="White" property but it will not print white text!
My tabcontrol that uses this style looks like this:
<TabControl Grid.Row="2" Style="{StaticResource MainMenuTab}">
<TabItem>
<TabItem.Header>
<TextBlock VerticalAlignment="Bottom" HorizontalAlignment="Center" Margin="0,0,0,5" Text="{x:Static UIStrings:ClientStrings.MainWindow_TabHeader_SingleWaveLength}"></TextBlock>
</TabItem.Header>
<TextBlock>TEST PANEL</TextBlock>
</TabItem>
</TabControl>
I know this is compicated but I would really love this to work.

Solution Found.
Based on HCL's post, I have found a solution. I am experiance the same exact problem I am trying to have the content presenter set the inherited dependence property. instead I simple tell the template to apply the dependance property, that way each tabitem is styled to have this property and therefore sets it for all it's children.
<Setter Property="ItemContainerStyle">
<Setter.Value>
<Style TargetType="TabItem">
<Setter Property="TextElement.Foreground" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid Background="{StaticResource Brush_ApplicationTabBackground}">
<Border Width="50" x:Name="BorderTab" Height="50" Margin="5" BorderThickness="1" ClipToBounds="True" BorderBrush="Transparent" Background="Transparent" CornerRadius="5">
<Rectangle x:Name="BackgroundRec" Fill="Transparent" Stroke="Transparent" Width="50" Height="50" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<ContentPresenter Name="TheHeaderContentPresenter" Width="50" Height="50" Margin="5" ContentSource="Header" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.Setters>
<Setter TargetName="BorderTab" Property="BorderBrush" Value="{StaticResource Brush_ApplicationTabHighlight}"/>
<Setter TargetName="BorderTab" Property="BorderThickness" Value="3"/>
<Setter TargetName="BackgroundRec" Property="Fill" Value="{StaticResource Brush_ApplicationTabHighlight}"/>
<Setter Property="Panel.ZIndex" Value="1"/>
</Trigger.Setters>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Trigger.Setters>
<Setter TargetName="BorderTab" Property="BorderBrush" Value="{StaticResource Brush_ApplicationTabBackground}"/>
<Setter TargetName="BorderTab" Property="BorderThickness" Value="0"/>
<Setter TargetName="BackgroundRec" Property="Fill" Value="{StaticResource Brush_ApplicationTabBackground}"/>
</Trigger.Setters>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Setter.Value>
</Setter>
All I've really dont is added the line:
<Setter Property="TextElement.Foreground" Value="White"/>
Before the control template! Also I took the white text out of the content presenter because it is useless.

Check this post, it looks to me as it is the same effect:
ContentPresenter within ControlTemplate cannot change attached dependency property
