Windows Phone 8.1 - Page Navigation

Coming from Windows Phone 8 I have never thought there will be a lot of changes done to the Windows Phone 8.1 code. Basically I'm just wondering how to do page navigation just like how you would do it on Windows Phone 8. To do that you should add:

NavigationService.Navigate(new Uri("/SecondPage.xaml", UriKind.Relative));

but that code doesn't work for Windows Phone 8.1.

Can someone please help me with this? If possible provide any links or documentation on all the new Windows Phone 8.1 methods.

Solution 1:

In Windows Phone 8.1, Page Navigation method is like this:

Frame.Navigate(typeof(SecondPage), param);

It means that you will navagate to 'SecondPage', and pass 'param' (a class based on object).

If you needn't to pass any parameters, You can use this:

Frame.Navigate(typeof(SecondPage));

You can find the documentation for this MSDN link

Solution 2:

In case you want to go back you can use:

if(this.Frame.CanGoBack)
{
this.Frame.GoBack();
}

If you want to go back on the click of back button, you need to override the hardwarebutton event:

HardwareButtons.BackPressed += HardwareButtons_BackPressed;

void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
        {
            Frame rootFrame = Window.Current.Content as Frame;
            if(rootFrame != null && rootFrame.CanGoBack)
            {
                rootFrame.GoBack();
                e.Handled = true;
            }

        }

Make sure to set e.Handled to true.
