how to make a Location Service Permission MessageBox - windows-phone-7

Question

I have submited a App but is not certified because this:
"This application uses the Location Service API to determine a user's location and show them events taking place nearby
however, it does not appear to contain a privacy policy that is accessible to users explaining how the application uses the
Location Service API."
And what i want to do is something like this
When user clicks in Policty Statement open a new window with settings page with my app location policies.
Can anyone help me? How can i add a link like in image?

Answer 1

You can navigate to a page using the Hyperlink control
<Textblock>
<Hyperlink NavigateUri="/PrivacyPage.xaml"
TargetName="_blank">Privacy Statement</Hyperlink>
</Textblock>
See MSDN for more info
I don't think you can put a hyperlink in a call to MessageBox.Show() though so you have to create your own Messagebox-like page.
The first time the app is launched you direct the user to your message page. E.g. using this in MainPage.xaml
OnNavigatedTo(...)
{
if(!AppSettings.HasMessageBeenShown)
{
AppSettings.HasMessageBeenShown=true;
NavigationContext.Navigate(new Uri("/MessagePage.xaml", UriKind.Relative));
}
}
