Passing a complex object to a page while navigating in a WP7 Silverlight application

Question

I have been using the NavigationService\'s Navigate method to navigate to other pages in my WP7 Silverlight app:

NavigationService.

Debatable solution, if anything, make it temporary.

Create this under the namespace of your application for whichever page necessary.

public static class VarsForPages {

    // Be sure to include public static.
    public static SomeClass SomeClassObject;
    public static List SomeList = new List();
    public static string SomeData = "SomeValue";

}

// The syntax for referencing the data
   VarsForPages.SomeClassObject; 
   VarsForPages.SomeList; 
   VarsForPages.SomeData;

Now you can reference SomeClassObject, SomeList, SomeData anywhere in the application.

Note: Like any global data, be weary of the many accesses & modifications which may be done to the global data. I say this, because I once had a list increase in size, but one of my pages in the application relied on the size of the list to be of some value, and this caused a bug. Don't forget, the data is global.
