Answer 1

Yes, that's what I was working on. I have a code sample:
MainPage.XAML.CS:
public sealed partial class MainPage : Page
public MainPage()
this.InitializeComponent();
protected override void OnNavigatedTo(NavigationEventArgs e)
List<string> MyList = new List<string>();
MyList.Add("A");
MyList.Add("B");
MyList.Add("C");
MyList.Add("D");
MyList.Add("E");
MyListView.ItemsSource = MyList;
MainPage.Xaml:
<Page
x:Class="REBAttachedProperty.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:REBAttachedProperty"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<ListView x:Name="MyListView">
<ListView.ItemTemplate>
<DataTemplate>
<RichEditBox Width="50" Height="30" local:BindableREBText.Text="{Binding}" ></RichEditBox>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
</Page>
BindableREBText.cs:
using System;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
namespace REBAttachedProperty
class BindableREBText
public static DependencyProperty TextProperty = DependencyProperty.RegisterAttached(
"Text",
typeof(string),
typeof(BindableREBText),
new PropertyMetadata(string.Empty, new PropertyChangedCallback(OnTextChanged))
public static void SetText(RichEditBox REB, string value)
REB.SetValue(TextProperty, value);
public static string GetText(RichEditBox REB)
return (string) REB.GetValue(TextProperty);
public static void OnTextChanged(DependencyObject sender, DependencyPropertyChangedEventArgs args)
RichEditBox REB = sender as RichEditBox;
string S = args.NewValue as string;
REB.Document.SetText(Windows.UI.Text.TextSetOptions.None, S);

If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with
undefined objects and unknown namespaces.
This is one-way binding. View Model can notify View, but View can not notify View Model.
Do You know how to improve this code to two-way binding?
