Navigating from a frame to another frame using code-behind

11-13-2009 6:39 AM |

Does anybody know how to duplicate this in code?

I am navigating from a second frame(which contains a sub menu) to a (content frame). The XAML works perfect, but I need to loan a XAP file first and then Navigate to the "ContentFrame".

So I need to Navigate after the code below which is in another XAML Page, so the FrameName.Navigate (new Uri("Page.xaml",UriKind.Relative)) method doesn't work because "FrameName" is not in the same page.

Private void Button_Click(object sender, System.Windows.RoutedEventArgs e)

{

WebClient c = new WebClient(); c.OpenReadCompleted += new OpenReadCompletedEventHandler(c_OpenReadCompleted); c.OpenReadAsync(new Uri("AnotherAssembly.xap", UriKind.Relative));
c.OpenReadCompleted += new OpenReadCompletedEventHandler(c_OpenReadCompleted);

Just a wild shot - can you send a local message to whoever has access to FrameName?

LocalMessageSender localMessageSender = new LocalMessageSender ( "FrameListener" );
localMessageSender .SendAsync ( "NavigateTo,Page.xaml");

LocalMessageReceiver LMR = new LocalMessageReceiver ( "FrameListener");
LMR3.MessageReceived += new EventHandler<MessageReceivedEventArgs>( FrameListener_LocalMessageReceived );
LMR3.Listen ();

void FrameListener_LocalMessageReceived ( object sender, MessageReceivedEventArgs e)
{
ParseNavRequest( e.Message );
}

If you are saying you can not find content frame in your childFrams's button click event.

((MainPage)App.Current.RootVisual).contentFrame will do the trick.

If you are have problems while download xap on demand , i recommand you to watch this video.

http://silverlight.net/learn/learnvideo.aspx?video=65687

It's only 20 minutes , and will guide you to establish a download on demand application from ground up.
