Question

I see there are similar posts on this topic but none answer my question. I am navigating to a silverlight page and I need to pass a value to the page. For security reasons, I cant use querystring.

What are the alternatives?

Thanks

You could simply add it to an Application Context object that can be shared between views. I use this approach in my current project e.g.

    public class ApplicationContext
    {

        #region Declarations

        // Static instance of the application class.
        private static ApplicationContext _instance;

        #endregion

        #region Constructor

        public ApplicationContext()
        {
        }

        // Static instance creator.
        public static ApplicationContext Instance()
        {
            if (_instance == null)
            {
                _instance = new ApplicationContext();
            }
            return _instance;
        }

        //Shared properties e.g. Is available between all views
        public SecurityContext UserContext { get; set; }
     }

To use from a view:

CurrentUserContext = ApplicationContext.Instance().UserContext 

So, before you navigate from one view to another simply populate relevant shared properties in the ApplicationContext object that can then be retrieved by other views.
