Я пытаюсь получить подтверждение не показывать через мой пользовательский модальный диалог. Я попытался установить Zindex диалогового окна и элементов этого шаблона. Есть идеи?

Это исходит из шаблона проверки:

<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>

Диалог:
