WPF Текстовое поле для использования символов паролей?

Question

У меня есть текстовое поле, которое я бы хотел использовать в качестве пароля? Можно ли сделать это? Я добавил PasswordChar = '*', но это не имеет никакого значения? Вот мой код.

public class AnimatedTextBox2 : TextBox 
{ 
    public static readonly DependencyProperty LabelProperty = 
     DependencyProperty.Register("Label", typeof(string), typeof(AnimatedTextBox2), 
      new FrameworkPropertyMetadata(null)); 

    public static readonly DependencyProperty HintProperty = 
     DependencyProperty.Register("Hint", typeof(string), typeof(AnimatedTextBox2), 
      new FrameworkPropertyMetadata(null)); 

    static AnimatedTextBox2() 
    { 
     DefaultStyleKeyProperty.OverrideMetadata(typeof(AnimatedTextBox2), 
      new FrameworkPropertyMetadata(typeof(AnimatedTextBox2))); 
     AnimatedTextBox2.PasswordChar = '*'; 
    } 

    public string Label 
    { 
     get { return (string)GetValue(LabelProperty); } 
     set { SetValue(LabelProperty, value); } 
    } 

    public string Hint 
    { 
     get { return (string)GetValue(HintProperty); } 
     set { SetValue(HintProperty, value); } 
    } 

    public static char PasswordChar { get; set; } 
} 

    <StackPanel Margin="0,0,-60,194.833" Height="62.731" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="458.167"> 
     <local:AnimatedTextBox2 
          Margin="139.5,0,151.5,15" 
          VerticalAlignment="Center" 
          Hint="Enter Password" 
          Label="Floating Label Text" Height="37.921" /> 

    </StackPanel> 

UPDATE control template добавлен ниже.

<Style TargetType="{x:Type local:AnimatedTextBox2}"> 
    <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}" />

Answer 1

Вы должны использовать PasswordBox вместо TextBox:

public class AnimatedTextBox2 : PasswordBox 
{ 
    // logic 
}
