Question

So I try to apply an image but cannot see any changes…

What do I am missing? Thanks!!

BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.UriSource = new Uri(@"pack://application:,,,/Images/bg1.jpg", UriKind.RelativeOrAbsolute);
bi.EndInit();
ImageBrush ib = new ImageBrush();
ib.TileMode = TileMode.Tile;
ib.ImageSource = bi;
ib.Stretch = Stretch.None;
RootGrid.Background = ib;

Answer 1

Try this instead:

var ib = new ImageBrush {
  ImageSource =
    new BitmapImage(
      new Uri(@"Images\bg1.jpg", UriKind.Relative)
    )
};

RootGrid.Background = ib;

Also, this is obvious, but make sure the image is actually at the right path and set to be Content in the Project.
