Position du bouton sur la carte - Windows Phone 8

Question

J'utilise Windows Phone 8 (Silverlight) et contrôle Microsoft.Phone.Maps.Controls.Map. Comment puis-je positionner le bouton, pour être dans le coin inférieur droit de la carte. J'ai essayé:

var grid = new Grid 
{ 
    HorizontalAlignment = HorizontalAlignment.Stretch, 
    VerticalAlignment = VerticalAlignment.Stretch 
}; 
var button = new Button 
{ 
    Content = "button", 
    HorizontalAlignment = HorizontalAlignment.Right, 
    VerticalAlignment = VerticalAlignment.Bottom,  
}; 
grid.Children.Add(centerButton); 
var mapOverlay = new MapOverlay 
{ 
     Content = grid 
}; 
var mapLayer = new MapLayer {mapOverlay}; 
map.Layers.Add(mapLayer); 

mais il reste toujours en haut à gauche seulement. Merci

var grid = new Grid() 
{ 
    HorizontalAlignment = HorizontalAlignment.Right, 
    VerticalAlignment = VerticalAlignment.Bottom,  
}; 
var button = new Button 
{ 
    Content = "button",   
}; 
grid.Children.Add(button); 
var mapOverlay = new MapOverlay 
{ 
     Content = grid 
}; 
var mapLayer = new MapLayer {mapOverlay}; 
map.Layers.Add(mapLayer);
