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： 结果

TextBox 正确采用了样式，但为什么 PasswordBox 不采用这种样式？

如果您将其包装Border在另一个中，Border一切都会按预期工作（我不知道为什么）。

作为奖励，您现在可以让PasswordBoxes 和TextBoxes “继承”同一个Style，保持良好和干燥。

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

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

<!-- TextBox -->
<Style x:Key="MyTextBox" TargetType="{x:Type TextBox}" BasedOn="{StaticResource MyControlInputBox}" />

<!-- PasswordBox -->
<Style x:Key="MyPasswordBox" TargetType="{x:Type PasswordBox}" BasedOn="{StaticResource MyControlInputBox}" />

不知何故Border内ControlTemplate不PasswordBox走MyControlBorder风格。

当您MyPasswordBox像这样修改样式时...然后它将起作用。

<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......但我不知道为什么MyControlBorder不应用。MyTextBox当你摆脱风格时，它甚至都不起作用。然后你只剩下MyControlBorderand MyPasswordBox...它也不起作用。
