如何在XAML中的密码框中制作内容为中心？

Question

我正在尝试在一个密码框中制作内容以在中心对齐时，当我们输入某些内容时，但我无法做到这一点。我已经尝试了这个链接

这是代码：

<PasswordBox Grid.Row="4" Password="{Binding Password,Mode=TwoWay}" BorderBrush="Transparent" HorizontalAlignment="Center" Margin="0" FontSize="25" HorizontalContentAlignment="Center"  VerticalContentAlignment="Center"  VerticalAlignment="Center" Width="550" Height="90" PlaceholderText="password" >
    <PasswordBox.Background>
        <ImageBrush  ImageSource="/Assets/Login/text-field.png"   AlignmentY="Bottom"></ImageBrush>
    </PasswordBox.Background>
</PasswordBox>

.

这是用于Windows Store App 。 但不确定他们是如何做的。如果有人能回答这个问题，我会感激。

问题似乎与 passwordboxstyle 。根边框元素没有TemplateBindings。

  <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" />
    </Border>
  </ControlTemplate>

.

尝试添加封装网格或将边框的横向组成它修改为如下所示：

  <ControlTemplate TargetType="{x:Type PasswordBox}">
   <Grid HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}">
    <Border x:Name="Border"
            HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
            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" />
    </Border>
   </Grid>
  </ControlTemplate>

.

然后将您的样式加载为staticresource
