Привязка модели из окна к пользовательским элементам управления

Question

Мне нужно связать "CommonViewModel" объект из кода с помощью "MainWindow" и его потомков "UserControl1" и "UserControl2" в режиме twoways

MainWindow.xaml

<Window x:Class="Testing.MainWindow"
    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"
    xmlns:local="clr-namespace:Testing"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">
    <StackPanel>
        <local:UserControl1/>
        <local:UserControl2/>
    </StackPanel>
</Window>

MainWindow.xaml.cs

public partial class MainWindow : Window
{
    public CommonViewModel commonViewModel = new CommonViewModel();
    public MainWindow()
    {
        InitializeComponent();
        this.DataContext = commonViewModel;
    }
}

UserControl1.xaml

<UserControl x:Class="Testing.UserControl1"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">
    <StackPanel >
        <TextBox Text="{Binding CommonProperity1,Mode=TwoWay}"/>
    </StackPanel>
</UserControl>

UserControl2.xaml

<UserControl x:Class="Testing.UserControl2"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">
    <StackPanel>
        <TextBox Text="{Binding CommonProperity2,Mode=TwoWay}"/>
    </StackPanel>
</UserControl>

Мой объект CommonViewModel.cs

public class CommonViewModel : NotifyChangeClass
{
    private string _Localtextdata1;
    private string _Localtextdata2;

    public string CommonProperity1
    {
        get { return _Localtextdata1; }
        set
        {
            _Localtextdata1 = value;
            NotifyPropertyChange("CommonProperity1");
        }
    }
    public string CommonProperity2
    {
        get { return _Localtextdata2; }
        set
        {
            _Localtextdata2 = value;
            NotifyPropertyChange("CommonProperity2");
        }
    }
}

public class NotifyChangeClass : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected void NotifyPropertyChange(string ProperityName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(ProperityName));
        }
    }
}

К сожалению, да, вы правы, это работает, ошибка была в рамках, ничего плохого в коде.

В любом случае, спасибо за попытку помочь.
