I'm trying to get the validation to not show through my custom modal dialog. I've tried setting the zindex of the dialog and and of the elements in this template. Any ideas?

This is coming from a validation template:

<ControlTemplate x:Key="ValidationTemplate">
        <DockPanel>
            <TextBlock Foreground="Red" FontSize="20" Panel.ZIndex="-10">!</TextBlock>
            <Border Name="validationBorder" BorderBrush="Red" BorderThickness="2" Padding="1" CornerRadius="3" Panel.ZIndex="-10">
                <Border.Resources>
                    <Storyboard x:Key="_blink">
                        <ColorAnimationUsingKeyFrames AutoReverse="True" BeginTime="00:00:00" Storyboard.TargetName="validationBorder" Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" RepeatBehavior="Forever">
                            <SplineColorKeyFrame KeyTime="00:00:1" Value="#00FF0000"/>
                        </ColorAnimationUsingKeyFrames>
                    </Storyboard>
                </Border.Resources>
                <Border.Triggers>
                    <EventTrigger RoutedEvent="FrameworkElement.Loaded">
                        <BeginStoryboard Storyboard="{StaticResource _blink}" />
                    </EventTrigger>
                </Border.Triggers>
                <AdornedElementPlaceholder/>
            </Border>
        </DockPanel>
    </ControlTemplate>

The dialog:

<UserControl
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
