PasswordBox不采用样式

问题描述：

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>

以及以下xaml代码:

and the following xaml code:

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

现在我得到了以下结果:

Now i got this results:

TextBox正确采用样式，但是为什么PasswordBox不采用样式?

The TextBox assume the style correctly, but why the PasswordBox does not assume the style?

答

以某种方式PasswordBox的ControlTemplate中的Border不采用MyControlBorder样式.

Somehow Border within ControlTemplate of PasswordBox does not take MyControlBorder style.

当您像这样修改MyPasswordBox样式时...它将起作用.

When you modify MyPasswordBox style like this... then it will work.

<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...但是我不知道为什么不应用MyControlBorder的原因.当您摆脱MyTextBox样式时，它甚至不起作用.然后只剩下MyControlBorder和MyPasswordBox ...它也不起作用.

I know it's not the best solution... but I can't figure out why MyControlBorder is not applied. It doesn't even work when you get rid of MyTextBox style. Then you are left only with MyControlBorder and MyPasswordBox ...it does not work either.
