I have created user control which contain TextBox and PasswordBox.
        <Converters:BoolToVisibilityConverter x:Key="boolToVisConverter" />
        <Converters:BoolToVisibilityConverter x:Key="boolToVisConverterReverse" />
    <Grid x:Name="LayoutRoot" removed="White" Width="Auto">
        <StackPanel Margin="5,5,5,5">
            <TextBox Text="{Binding TextValue}" Visibility="{Binding IsTextBox,Converter={StaticResource boolToVisConverter}}" BorderBrush="Green" />
            <PasswordBox Password="{Binding TextValue}" Visibility="{Binding IsTextBox,Converter={StaticResource boolToVisConverterReverse}}" BorderBrush="Red" />

public partial class RestrictedBox : UserControl
        public RestrictedBox()
        public string TextValue
            get { return (string)GetValue(TextValueProperty); }
            set { SetValue(TextValueProperty, value); }
        public static readonly DependencyProperty TextValueProperty = DependencyProperty.Register("TextValue", typeof(string), typeof(RestrictedBox), new PropertyMetadata(default(string)));
        public bool IsTextBox
            get { return (bool)GetValue(IsTextBoxProperty); }
            set { SetValue(IsTextBoxProperty, value); }
        public static readonly DependencyProperty IsTextBoxProperty = DependencyProperty.Register("IsTextBox", typeof(bool), typeof(RestrictedBox), new PropertyMetadata(default(bool)));
Now i added above User Control to my LoginView.xaml page
<control:RestrictedBox TextValue="Imdadhusen" IsTextBox="True"   />

Now i run the application but the TextValue = "Imdadhusen" is not bind with my text box and the second property IsTextBox is set to True that means it will automatically hide Passwordbox else Textbox.

Any help would be appreciated!
Thanks, Imdadhusen

Solution 1

UserControls do not register themselves as the data context automatically so the binding inside the user control won't have anything to bind to.

I have added following line my UserControl codebehind to enable default binding.

public RestrictedBox()
     this.DataContext = this;
