c# - Show image in Full screen -

I am working on the Windows Phone 8 app and there is an image view in XAML :

  & lt; Image Name = "Image" Grid. Line = "0" visibility = "collapsed" width = "auto" height = "auto" = "image_tap" horizontal alignment = "center" vertical alignment = "center" margin = "1,1,1,1" This event is called  tap = "Image_tap"  now, when I tap on the image, then I can use the same picture without any time Want to show in the screen up and down, how to get it?  
  
 
 
 Below is the  ApplicationBar  and the top bar is  SystemTray . If you create a new page without the  ApplicationBar  and you are false from  SystemTray.IsVisible , then you have a full screen page now, on the root  grid , just place one  image  and you can use that page as a full screen viewer.  
  & lt; Phone: Phone Application Page: Class = "SimpleApp.FullScreenPage" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/ Winfx / 2006 / xaml "xmlns: phone =" clr-namespace: microsoft.phone control, assembly = microsoft.phone "xmlns: shell =" clr- namespace: microsoft.phone shell; assembly = microsoft.phone "xmlns: D = "Http://schemas.microsoft.com/expression/blend/2008" xmlns: mc = "http://schemas.openxmlformats.org/markup-compatibility/2006" fontfamily = "{static resorsphonefontsfamily normal}" fontsis = "{StaticResource PhoneFontSizeNormal}" Foreground Mi = "{StaticResource PhoneForegroundBrush}" Supported orientation = "portrait" orientation = "Portrait" MC: Ignorable = "d" shell: SystemTray.IsVisible = "False" & gt; & Lt; Image name = "myImage" horizontal alignment = "statch" vertical alignment = "statch" stretch = "uniform" /> & Lt; / Phone: PhoneApplicationPage & gt;   
 In the main page where you can tap the image:  
  Private zero myIgg_Tap (Object Sender, System.Windows.Input.GestureEventArgs e) {string context = (Bitmap image as source) .UriSource.ToString ();) as source. Navigation service Navigate (New Uri (string.conquet ("/ Page1.xaml? Context =", reference), Uricund.relative orsolute); }   
 In the fullscreenpage:    Safe Override was navigated to zero (Navigation EventVerses E) {string context = this.NavigationContext.QueryString ["context"] ; MyImage.Source = New Bitmap Image (new Uri (reference, UriKind.relative orsolute)); Base.OnNavigatedTo (e); }
