[Windows Phone 7] how to navigate between pages and pass values between pages

WP7 navigation page:

 
Navigationservice. navigate (New uri ("/page1.xaml", urikind. Relative ));
 

Value Transfer between pages in WP7:

The value transfer between WP7 pages is similar to that between common web pages.

 
This. navigationservice. navigate (New uri ("/page1.xaml? Pagetitle = Hello ", urikind. Relative ));
 

Another page value:

 
This. pagetitle. Text = navigationcontext. querystring ["pagetitle"]. tostring ();
 

Of course, you can directly use the applicationProgramStatus to save the value:

 
Phoneapplicationservice. Current. State ["key"] = "value ";
 

You can also use global variables to store values and use static directly. However, this method is generally not recommended.

Note: To access the value between pages, try to operate in the onnavigatedfrom and onnavbigatedto events of heavy load.
