PasswordBox不承担样式

Question

我有以下样式定义:

<!-- Border -->
<Style x:Key="MyControlBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderBrush" Value="DarkKhaki" />
    <Setter Property="Background" Value="White" />
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="CornerRadius" Value="10" />
</Style>

<!-- TextBox -->
<Style x:Key="MyTextBox" TargetType="{x:Type TextBox}">
    <Setter Property="Height" Value="30" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TextBoxBase}">
                <Border Name="TextBoxBorder" Style="{StaticResource MyControlBorder}">
                    <ScrollViewer x:Name="PART_ContentHost"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<!-- PasswordBox -->
<Style x:Key="MyPasswordBox" TargetType="{x:Type PasswordBox}">
    <Setter Property="Height" Value="30" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Control}">
                <Border Name="Border" Style="{StaticResource MyControlBorder}">
                    <ScrollViewer x:Name="PART_ContentHost" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

和以下xaml代码:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <TextBox Grid.Row="0" Style="{StaticResource MyTextBox}" />
    <PasswordBox Grid.Row="1" Style="{StaticResource MyPasswordBox}" />
</Grid>

现在我得到了这个结果:

TextBox正确地假设了样式,但为什么PasswordBox不承担样式？

不知怎的，里面Border不带风格。ControlTemplatePasswordBoxMyControlBorder

当你MyPasswordBox像这样修改样式时......然后它就会起作用。

<Style x:Key="MyPasswordBox" TargetType="{x:Type PasswordBox}">
<Setter Property="Height" Value="30" />
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type Control}">
            <Border Name="Border" BorderBrush="DarkKhaki" Background="White" BorderThickness="1" CornerRadius="10">
                <ScrollViewer x:Name="PART_ContentHost" />
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>

我知道这不是最好的解决方案...但我不明白为什么MyControlBorder不应用。当你摆脱MyTextBox风格时它甚至不起作用。然后你就只剩下MyControlBorder……MyPasswordBox它也不起作用。
