how to bind one TextBox

Hello
I have been looking how to bind one text box on IdeaBlade

I know the DataForm and DataGrid use ItemsSource="{Binding Employees}" Property

but  my TextBox

<TextBox Grid.Column="1" Grid.Row="4" Height="23" HorizontalAlignment="Left" Margin="1" Name="Employee_WorkPhoneTextBox" Text="{Binding Employee_WorkPhone}" VerticalAlignment="Center" Width="230" HorizontalContentAlignment="Left" IsTabStop="True" MaxLength="20"/>

Also tried my Prior Ria Binding , but it does not work either on IdeaBlade

<TextBox Grid.Column="1" Grid.Row="4" Height="23" HorizontalAlignment="Left" Margin="1" Name="Patient_WorkPhoneTextBox" Text="{Binding Path=Emplyee_WorkPhone, Mode=TwoWay, NotifyOnValidationError=true, ValidatesOnExceptions=true, TargetNullValue=''}" VerticalAlignment="Center" Width="230" HorizontalContentAlignment="Left" IsTabStop="True" MaxLength="20"/>

the DetailsGrid where this TextBox is located, is bound to
<Grid DataContext="{Binding Employees}"

I followed
http://www.ideablade.com/DevForceSilverlight/DevForceSilverlight_DevelopersTour.aspx

on the same form I have a DataGrid for testing purposes and I can see the data on the grid , but not in my TextBox

what I am doing wrong ?

IdeaBlade is pretty fast compared to Ria Services

Have a look at one of the Mini-Demo apps, e.g., either the WPF or Silverlight version in the Business Object Persistence Code Samples.

They have an extremely simple UI consisting basically of a TextBlock whose Text property is bound to a property in a viewmodel class.
