Can I set parameter using NavigationContext.QueryString? (Windows Phone)

Question

Can I pass value to Navigation Context like this:

NavigationContext.QueryString["param1"] = "PARAM1";

Is it a good way to set parameter?

Answer 1

First of all, why you need to store some parameters in NavigationContext.QueryString? There are exists another good places for this.

If you want to pass parameters to another page, use this:

NavigationService.Navigate(new Uri("SomePage.xaml?param1=PARAM1"))

if you need to save some values to the state dictionary, you can use PhoneApplicationService.Current.State (global) or PhoneApplicationPage.State (page specific)
