无法从主视图绑定UserControl

问题描述

限时删除！！

我创建了包含TextBox和PasswordBox的用户控件.

RestrictedBox.xaml

I have created user control which contain TextBox and PasswordBox.

RestrictedBox.xaml

<UserControl.Resources>
        <Converters:BoolToVisibilityConverter x:Key="boolToVisConverter" />
        <Converters:BoolToVisibilityConverter x:Key="boolToVisConverterReverse" />
    </UserControl.Resources>
    <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" />
        </StackPanel>
    </Grid>

RestrictedBox.xaml.cs

RestrictedBox.xaml.cs

public partial class RestrictedBox : UserControl
    {
        public RestrictedBox()
        {
            InitializeComponent();
        }

        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)));
    }

现在，我在用户控件上方添加到了 LoginView.xaml 页面

Now i added above User Control to my LoginView.xaml page

<control:RestrictedBox TextValue="Imdadhusen" IsTextBox="True"   />

现在，我运行该应用程序，但TextValue ="Imdadhusen"未与我的文本框绑定，并且第二个属性IsTextBox设置为True，这意味着它将自动隐藏Passwordbox，否则将隐藏Textbox.

任何帮助将不胜感激！

谢谢，Imdadhusen

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

推荐答案

public RestrictedBox()
{
     InitializeComponent();
     this.DataContext = this;
}

谢谢，
