I have developed an Universal app that uses a login form, that allowing users to connect or to create an account.
It is a simple page that looks like this:

This XAML code is also very simple:
<ScrollViewer>
<StackPanel>
<TextBlock x:Uid="loginRegisterTextblockMessage"
Style="{StaticResource TitleTextBlockStyle}"
Text="Remplissez vos informations d'inscription" />
<TextBox x:Uid="loginRegisterTextboxOrganizationURL"
Header="Organisation ou URL"
IsSpellCheckEnabled="False"
IsHitTestVisible="True"
IsTextPredictionEnabled="False"
Text="{Binding OrganizationURL, Mode=TwoWay}" />
<TextBox x:Uid="loginRegisterTextboxLastName"
Header="Nom"
Text="{Binding LastName, Mode=TwoWay}" />
<TextBox x:Uid="loginRegisterTextboxFirstName"
Header="Prénom"
Text="{Binding FirstName, Mode=TwoWay}" />
<TextBox x:Uid="loginRegisterTextboxEmail"
Header="Email"
InputScope="EmailSmtpAddress"
Text="{Binding Email, Mode=TwoWay}"/>
<PasswordBox x:Uid="loginRegisterPasswordboxPassword"
Header="Mot de passe"
Password="{Binding Password, Mode=TwoWay}" />
<PasswordBox x:Uid="loginRegisterPasswordboxConfirmPassword"
Header="Confirmez le mot de passe"
Password="{Binding PasswordConfirmation, Mode=TwoWay}" />
<CheckBox x:Uid="loginRegisterCheckboxTermsOfUse"
IsChecked="{Binding TermsOfUse, Mode=TwoWay}" >
<TextBlock Style="{StaticResource BaseTextBlockStyle}">
<Run x:Uid="loginRegisterTextblockTermsOfUse1"
Text="J'accepte les " />
<Underline>
<Hyperlink x:Uid="loginRegisterHyperlinkTermsOfUse"
NavigateUri="http://termsofuse.html" >
<Run x:Uid="loginRegisterTextblockTermsOfUse2"
Text="conditions générales d'utilisation" />
</Hyperlink>
</Underline>
</TextBlock>
</CheckBox>
<Button x:Uid="loginRegisterButtonRegister"
Content="S'inscrire"
Command="{Binding RegisterCommand}" />
</StackPanel>
</ScrollViewer>
But I meet a "problem" for navigating between each fields of this page:

=> The user must click outside of a TextBlock to hide the keyboard and select the next field: this is not very user-friendly
I took a look at a similar "system" form: the page used to create an account to access to the Windows Store.
The page looks very similar to my own page:

But it is there possible to activate the next field by clicking on its header:
The focus moved on the field and the keyboard is also automatically displayed:

If I click on the the next header "Nom d'utilisateur", I can see that the next field is now "Domaine", by moving automatically into the displayed content:

=> Is there an easy way to reproduce this comportment? Is it based on the "Header" of the "TextBox", or by using seperated "TextBlock" to show the header?
