If you need to put an image as a background of any control (button or grid, didn't understancd you), just set, in code, the Background property to an ImageBrush with an ImageSource of your image.

This code is for button, edit it ...

Button button = new Button();
button.Margin = new Thickness(220, -880, 0, 0);
button.Width = w;
button.Height = h;
/////////////////////////////////////////////////////////
ImageBrush berriesBrush = new ImageBrush();
berriesBrush.ImageSource = new BitmapImage(new Uri(@"Image/country.PNG", UriKind.Relative));
button.Background = berriesBrush;
button.BorderThickness = new Thickness(0);

This might you ...
