Windows Phone 8.1 - Page Navigation

Question

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.

Answer 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

And If I want to go back, clicking the hardware back button doesn't work so would I have to add the hardware back button pressed event and then enter the page which I want? or is their an easier way? – Apeman

You can use NavigationHelper in your SecondPage, so that you don't need to add event handler.For example, you can create a BasicPage instead of BlankPage as your SecondPage. And you will see it. – Solifidian

@Devi Prasad You should define a class which contains your multiple parameters. – Solifidian

This method worked for me in forward navigation. I added it to the click event in xmal.cs file. – Circumvent

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.

How to pass Multiple Paraeters – Cooler

Use array or List<object> , put your parameters in it, and pass the array or the List<object> in the parameter. Do you want a sample ? – Vespertilionine

Answer 4

To send multiple parameters: Its quite late to answer but might help someone. You can create a custom class, set your parameters in it and send its object as a parameter to your target page.

For example. Your custom class:

public class CustomDataClass
{
public string name;
public string email;
} 

CustomDataClass myData = new CustomDataClass();
myData.name = "abc";
myData.email = "[email protected]";

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

And then on the target page you can retrieve in OnNavigatedTo function like this:

protected override void OnNavigatedTo(NavigationEventArgs e)
{
CustomDataClass myData2 = e.Parameter as CustomDataClass;
string name = myData2.name;
string email = myData2.email;
}

Hope it helps.
