Web developers will find themselves in familiar territory with the navigation in Windows Phone 7.
NavigationService Class
Navigate to another page:
|
1 |
NavigationService.Navigate(new Uri("NewPage.xaml", UriKind.Relative)); |
Navigate to another page (with parameters):
|
1 |
NavigationService.Navigate(new Uri("NewPage.xaml" + "?ID=" + "15", UriKind.Relative)); |
NavigationContext Class
If a parameter was passed to the destination page using query string, NavigationContext class allows to read the query string as follows
|
1 2 |
string ID; NavigationContext.QueryString.TryGetValue("ID", out ID); |
Navigation History
Navigation history is exposed as a read-only enumeration through the property called NavigationServices.BackStack,
There are additional methods exposed for going back and forward one step at a time. It is a good practice to check for the CanGoBack and CanGoForward property before calling the navigation methods to make sure there is more in the history to go back or forward.

if (NavigationService.CanGoBack) { NavigationService.GoBack(); } if (NavigationService.CanGoForward) { NavigationService.GoForward(); } |
