Maybe you need this

void MoveToPoint(UIElement sender, Point point)
{
    Canvas.SetLeft(sender, point.X - sender.RenderTransformOrigin.X * sender.ActualWidth);
    Canvas.SetTop(sender, point.Y - sender.RenderTransformOrigin.Y * sender.ActualHeight);
}

to Xaml (patern MVVM): you need write converter and for properties Canvas.Left and Canvas.Top use Binding. It's more code than previously.

Example Converter (example 6) http://www.codeproject.com/Articles/29054/WPF-Data-Binding-Part

In converter need send 2 parameters sender.RenderTransformOrigin.X and ActualWidth.
