Update:

The answer of this question is a better solution: Passing data from page to page

Code:

PhoneApplicationService.Current.State["MyObject"] = yourObject;
NavigationService.Navigate(new Uri("/view/Page.xaml", UriKind.Relative));

//In the Page.xaml-page
var obj = PhoneApplicationService.Current.State["MyObject"];

You can just add parameters to the URL, like this:

NavigationService.Navigate(new Uri("/Page.xaml?object1=" + obj + "&object2=" + obj2, UriKind.Relative));

Otherwise, create a wrapper object that holds all of your object (like used in the MVVM pattern):

public class Container
{
    public object Object1 { get; set; }
    public object Object2 { get; set; }
}

var container = new Container { Object1 = obj, Object2 = obj2 };
NavigationService.Navigate(new Uri("/Page.xaml?object1=" + container, UriKind.Relative));

I have the same doubt, how can I get the container object in the page view? – danielrvt Feb 11 '14 at 23:58
@danielrvt did you check my update? Check the link to the other question in my answer for more info. :) – Abbas Feb 12 '14 at 08:14
@danielrvt, you need this method on the page: `protected override void OnNavigatedTo(NavigationEventArgs e) { //code with the Container like the Abbas answer }` – Dherik Dec 12 '14 at 21:47

Prefer the first method. – Tealc Wu Dec 29 '14 at 07:17
@Tealc Wu: that is also the better approach. – Abbas Dec 29 '14 at 12:41

Im not sure what you mean by object. Do you mean an ACTUAL object that inherits from Object or do you mean a value such as String value or int value.

regardless:

NavigationService.Navigate(new Uri("/Page.xaml?object1="+obj+"&object2="+obj2, UriKind.Relative));

This should work for you.

You only can pass strings between pages in this way. Use PhoneApplicationService.Current.State["MyObject"] to save any object you would like to pass. – Tealc Wu Dec 29 '14 at 07:17

1st link is broken, plus you just cannot say go and learn whole MVVM for every single question about WP development. – Teoman shipahi Oct 21 '14 at 02:34
