Entity Framework and Navigation window

Hi all :)

I am trying to implement  Julie Lerman's entity framework for Master-Detail scenario on Navigation Window.

when I try to drag and drop a control ( for example a datagrid) on a Page it doesn't display the details on that control when i debug. 

For example, the drag and drop EF doesn't work on my Page..

<NavigationWindow x:Class="ProjectName.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Source="Page1.xaml"
        d:DesignHeight="534" d:DesignWidth="1051"  />

<Page x:Class="ProjectName.Page1"
      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" />

how to overcome this issue, I need navigation because, my app should have mutilple pages to move forward and backward. is their any other way to achieve this ?

kindly help.
