I am trying to perform fade in transition on a Window. I am able to do the transition but only to the contents of the window. I mean the frame of the window and title bar are not transforming like the content in it. Please check the XAML code below and see what has to be done for the whole window to fade in. Please dont tell me to set the allow transparency to true and window style to none. I want the title bar to fade in as well.

<Window x:Class="WpfApplication6.newwindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="newwindow" Height="295" Width="371" PreviewStylusInRange="Window_PreviewStylusInRange">
<Window.Triggers>
    <EventTrigger RoutedEvent="Window.Loaded">
        <BeginStoryboard>
            <Storyboard>
                <DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:2" FillBehavior="HoldEnd" />
            </Storyboard>
        </BeginStoryboard>
    </EventTrigger>
</Window.Triggers>


<Grid Height="257" Width="349">
    <Label Content="Label" Height="28" HorizontalAlignment="Left" Margin="115,0,0,112" Name="label1" VerticalAlignment="Bottom" Width="127" Background="#FFDB1F1F" />


    </Grid>

I am using VS 2010 with .NET 3.5.

Thank you.
