I should have checked first, apparently it's not supported. I don't know how
you SL guys can inflict so much pain upon yourselves :)
I suppose it could be created by something like this:
public static T FindResource<T>(this FrameworkElement element, string name)
{
var resource = element.Resources[name];
if (resource != null)
{
return (T)resource;
}
var parent = element.Parent as FrameworkElement;
if (parent == null) throw new Exception();
return parent.FindResource<T>(name);
}
