Public Event PropertyChanged As PropertyChangedEventHandler Implements INotifyPropertyChanged.PropertyChanged

Private _name As String

亲切问候,，

Kumar将LayoutRoot的datacontext属性设置为您的地址。然后在xaml中执行以下操作：

<TextBox ... Text="{Binding Name}" />

VB简单地址类：

Public Class Address

    Private _name As String = "Some Text"

    Public Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            _name = value
        End Set
    End Property
End Class

请注意，我只设置了一次DataContext，这是针对LayoutRoot的。

为了给您一个简单的示例，我添加了我的答案。您的代码隐藏已将LayoutRoot.DataContext设置为address，但已被注释掉。很好！我希望我的回答是有帮助的。

<TextBox ... Text="{Binding Name}" />

<UserControl x:Class="VBSLTest.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <TextBox Height="23" HorizontalAlignment="Left" Margin="12,12,0,0" Name="TextBox1" VerticalAlignment="Top" Width="192" Text="{Binding Name}" />
    </Grid>
</UserControl>

Partial Public Class MainPage
    Inherits UserControl

    Public Sub New()
        InitializeComponent()
        Dim address As Address
        Address = New Address()
        LayoutRoot.DataContext = address
    End Sub

End Class

Public Class Address

    Private _name As String = "Some Text"

    Public Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            _name = value
        End Set
    End Property
End Class
