          Value="120" />
  <Setter Property="MinHeight"
          Value="20" />
  <Setter Property="AllowDrop"
          Value="true" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type PasswordBox}">
        <Border x:Name="Border"
                CornerRadius="2"
                Padding="2"
                BorderThickness="1">
          <Border.Background>
            <SolidColorBrush Color="{DynamicResource ControlLightColor}" />
          </Border.Background>
          <Border.BorderBrush>
            <SolidColorBrush Color="{DynamicResource BorderMediumColor}" />
          </Border.BorderBrush>
          <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="CommonStates">
              <VisualState x:Name="Normal" />
              <VisualState x:Name="Disabled" />
              <VisualState x:Name="MouseOver" />
            </VisualStateGroup>
          </VisualStateManager.VisualStateGroups>
          <ScrollViewer x:Name="PART_ContentHost" />
