load a specified user control and its code behind on demand

Hi Peter + Daisy,
As far as I can understand, the code behind of a specified user control would fail
the following code:

(UserControl)XamlReader.Load(new FileStream(_userControlFilePath, FileMode.Open));

Is there a way to load a specified user control and its code behind, just as we do with a specified page? For example,

 NavigationService NS = fm.NavigationService;
 NS.Navigate(new Uri("pages/Page2.xaml", UriKind.Relative));

Thanks.

Hi Jenny,
on demand you can load only xaml code. If you want to use CodeBehind you must translate this code. The best way is to use translated UserControlLibrary. An other way is to use Binding to properties of prepared (translated) object like ViewModel. If you get untranslated progeamm code you can translate this code on demand (CodeDomProvider) and then load xaml code.

“on demand you can load only xaml code.”

Thanks a lot, Peter. This is what I feel about user control. Thank you for your confirmation,
