How to create a user control that includes a dataform in Silverlight 4?

Question

I created a custom UserControl named EditUserInfo, that includes a DataForm control. In the UserControl I created a Dependency Property of type UserInformation class named CurrentItem.

The MainPage contains this user control, and in it's Loaded event I set UserControl's CurrentItem property to a newly created UserInformation object.

The UserInformation class is decorated with attributes for displays. When I run the application, the dataform genarates only the header but labels and textboxes missing. When I use the dataform individually in a page everything works well.

Here is the CurrentItem dependency Property:

public partial class UserinfoEditControl : UserControl { public UserinfoEditControl() { // Required to initialize variables InitializeComponent(); }

    public UserInformation CurrentItem
    {
        get { return (UserInformation)GetValue(CurrentItemProperty); }
        set { SetValue(CurrentItemProperty, value); }
    }

    public static readonly DependencyProperty CurrentItemProperty =
        DependencyProperty.Register("CurrentItem", typeof(UserInformation), typeof(UserinfoEditControl), null);}

Here is the declaration of the UserControl, the DataContext set to RelativeResource Self:

<UserControl
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:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"
mc:Ignorable="d"
x:Class="WebSzamla.Controls.UserinfoEditControl"
DataContext="{Binding RelativeSource={RelativeSource Self}}"
d:DesignWidth="245" d:DesignHeight="93">

In the DataTemplate I set the DatatBindigs:

        <DataTemplate x:Key="RegistrationEditTemplate">
        <StackPanel VerticalAlignment="Top" MinWidth="400" >
            <toolkit:DataField >
                <TextBox Text="{Binding email_address, Mode=TwoWay}" />
            </toolkit:DataField>
            <toolkit:DataField >
                <PasswordBox Password="{Binding password, Mode=TwoWay}" />
            </toolkit:DataField>
            <toolkit:DataField >
                <PasswordBox Password="{Binding confirm_password, Mode=TwoWay}" />
            </toolkit:DataField>
            <toolkit:DataField >
                <TextBox Text="{Binding security_question, Mode=TwoWay}" />
            </toolkit:DataField>
            <toolkit:DataField >
                <PasswordBox Password="{Binding security_answer, Mode=TwoWay}" />
            </toolkit:DataField>
        </StackPanel>
    </DataTemplate>

In the MainPage I inserted my UserControl and set it's currentItem property to a new UserInformation object:

    public Registration()
    {
        InitializeComponent();

        Loaded += (s, e) =>
        {
             EditUserInfo.CurrentItem = newUser;
        };
    }

Does anybody knows, why it doesn't work? Thanks in advance
