Hi, How can I programmatically set a button's template?

Polygon buttonPolygon = new Polygon();
buttonPolygon.Points = buttonPointCollection;
buttonPolygon.Stroke = Brushes.Yellow;
buttonPolygon.StrokeThickness = 2;

// create ControlTemplate based on polygon
ControlTemplate template = new ControlTemplate();
template.Childeren.Add(buttonPolygon); // This does not work! What's the right way?

//create button based on controltemplate
Button button = new Button();
button.Template = template;

So I need a way to set my Polygon as the button's template.. Suggestions?

Thanks.
