NavigationService

NavigationService enables to download content within the context of browser style navigation. There are 2 ways to navigate content:

1. To navigate the content we need to use Navigate() method of NavigationService and passing the object to it.
   • NavigationService.Navigate(Object)
   • NavigationService.Navigate(Object, Object)
2. To navigate the content between pages we can use another overload of Navigate() method which takes a uniform resource identifier (URI) as one of the parameters and send the object to this URI:
   • NavigationService.Navigate(Uri)
   • NavigationService.Navigate(Uri, Object)
   • NavigationService.Navigate(Uri, Object, Boolean)

When content is navigated through a URI, NavigationService will return an object that contains the content.

Code Example

Let’s see an example of how to navigate content between pages.

Consider we have 2 pages – page1, page2. On click of submit button on page1,we need to send some data to Page2.

Code for submit button on Page1

private void submit_click(Object sender, RoutedEventArgs e)
{
  NavigationService.Navigate(new Uri(“/Page2.xaml?msg=”+ txtName.text,Uri.Relative) ); 
}

Code for retrieving data on Page2

protected override void onNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    base.onNavigatedTo(e); 
    string msg;
    if(NavigationContext.QueryString.TryGetValue(“msg”,out msg))
    {  
      string name = msg;
    }  
}
