Changing button background on button click

Question

I am making a store app on Visual Studio 2013.

I wish to change the background Image of a button when the button is pressed. I have searched internet to vain. I wrote following code :-

             Uri x = new Uri("/Assets/hello.png", UriKind.RelativeOrAbsolute);
             ImageBrush brush = new ImageBrush();
             BitmapImage bmp = new BitmapImage();
             bmp.UriSource = x;
             brush.ImageSource = bmp;
             bt.Background = brush;                          //bt is name of button

I even wrote this also :-

             Uri x = new Uri("/Assets/hello.png", UriKind.RelativeOrAbsolute);
             ImageBrush brush = new ImageBrush();

             brush.ImageSource = new BitmapImage(x);
             bt.Background = brush;   

       

But I am receiving same error each time saying "An exception of type 'System.ArgumentException' occurred in mscorlib.dll but was not handled in user code"

Please help. I am totally exhausted....

Answer 1

Use a non-relative URI ("ms-appx:///assets/hello.png") instead of a relative URI.

See the example code in the BitmapImage documentation at http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.media.imaging.bitmapimage.aspx
