Generating WPF Password

I am currently trying to do the following: If no password is entered, the text "Password" should be displayed.

But with my template the password is not displayed and if I use a decorator or scrollviewer I cannot change the text color.

Do you have any ideas for achieving this?

Here's my style code:

<Style TargetType="{x:Type PasswordBox}" x:Key="Password">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="PasswordBox">
                    <Grid>
                        <PasswordBox Background="{StaticResource BrushDark}" Foreground="{StaticResource BrushTextNormal}" BorderBrush="{StaticResource BrushBorderInput}" BorderThickness="1"/>
                        <TextBlock HorizontalAlignment="Left"
                            VerticalAlignment="Center"
                            Text="Password"
                            Margin="5,0,5,0"
                            Foreground="#ff808080"
                            IsHitTestVisible="False"
                            x:Name="UserMessage"
                            Visibility="Hidden"/>
                        <!--<ScrollViewer Foreground="{StaticResource BrushTextNormal}" Background="{StaticResource BrushTextNormal}" x:Name="PART_ContentHost"/>-->
                        <!--<Decorator TextBlock.Foreground="White" x:Name="PART_ContentHost"/>-->
                    </Grid>
                    <ControlTemplate.Triggers>
                        <MultiTrigger>
                            <MultiTrigger.Conditions>
                                <Condition Property="Tag" Value=""/>
                                <Condition Property="IsKeyboardFocusWithin" Value="False"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="Visibility" TargetName="UserMessage" Value="Visible"/>
                        </MultiTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

If you create a custom ControlTemplate

for PasswordBox

or TextBox

, you need to put ScrollViewer

with name x:Name="PART_ContentHost

instead of innerPasswordBox

From Password and PasswordBox Templates

PART_ContentHost is a visual element that can contain a FrameworkElement. This element displays the text PasswordBox.



And change Foreground

like another one Setter

on you Style

. Also, as a side node, I would do the same with Background

and use TemplateBinding

in your ControlTemplate

. This will give a lot of flexibility and allow you to change Background

and / or Foreground

manually without changingControlTemplate

<Style TargetType="{x:Type PasswordBox}" x:Key="Password">
   <Setter Property="Foreground" Value="{StaticResource BrushTextNormal}" />
   <Setter Property="Background" Value="{StaticResource BrushDark}"/>
   <Setter Property="Template">
      <Setter.Value>
         <ControlTemplate TargetType="{x:Type PasswordBox}">
            <Grid Background="{TemplateBinding Background}">
               <ScrollViewer x:Name="PART_ContentHost" .../>
               <TextBlock .../>               
            </Grid>
            <ControlTemplate.Triggers>
               <!-- removed -->
            </ControlTemplate.Triggers>
         </ControlTemplate>
      </Setter.Value>
   </Setter>
</Style>
