  <Setter Property="Foreground"
          Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" />
  <Setter Property="Background"
          Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
  <Setter Property="FocusVisualStyle"
          Value="{x:Null}" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type DocumentViewer}">
        <Border BorderThickness="{TemplateBinding BorderThickness}"
                BorderBrush="{TemplateBinding BorderBrush}"
                Focusable="False">

                      Content="Two Pages" />
            </ToolBar>

            <ScrollViewer Grid.Row="1"
