Background image Windows Phone 7 - windows-phone-7

Question

I have a little question, I want to change the background of my application with C#.
I tried this code :
var app = Application.Current as App;
var imageBrush = new ImageBrush
{
ImageSource = new BitmapImage(new Uri(imageName, UriKind.Relative))
};
app.RootFrame.Background = imageBrush;
But it doesn't work, the background is dark.. I tried to do :
app.RootFrame.Background = new SolidColorBrush(Colors.Blue);
And it works well. So I don't understand where is the problem, my image is 480*800 px and I set Build Action to Content and Copy to Output Directory to Copy if newer .
Thanks for all

Answer 1

maybe you can try it
var app = Application.Current as App;
if (app == null)
return;
var imageBrush = new ImageBrush
{
};
var uu = new BitmapImage(new Uri(imageName, UriKind.Relative));
uu.CreateOptions = BitmapCreateOptions.None;
imageBrush.ImageSource = uu;
app.RootFrame.Background = imageBrush;
Mark: uu.CreateOptions = BitmapCreateOptions.None;

Answer 2

I'm doing almost the exact same thing successfully with an image, except I'm setting the image as the background to a panorama control. I know someone else had the same problem you did in this post so I suggested setting the background of the LayoutRoot or other control instead of the app.RootFrame.

Thank you both !!
I had previously tried the two solutions separately and it didn't work. But together it works perfectly!
The code :
var imageBrush = new ImageBrush
{
};
var uu = new BitmapImage(new Uri("/Images/image.png", UriKind.Relative));
uu.CreateOptions = BitmapCreateOptions.None;
imageBrush.ImageSource = uu;
LayoutRoot.Background = imageBrush;
