Point _anchorPoint;
       Point _currentPoint;
       bool _isInDrag;
       private readonly TranslateTransform _transform = new TranslateTransform();

       private void root_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
       {
           var element = sender as FrameworkElement;
           _anchorPoint = e.GetPosition(null);
           if (element != null) element.CaptureMouse();
           _isInDrag = true;
           e.Handled = true;
       }

       private void root_MouseMove(object sender, MouseEventArgs e)
       {
           if (!_isInDrag) return;
           _currentPoint = e.GetPosition(null);

           _transform.X += _currentPoint.X - _anchorPoint.X;
           _transform.Y += (_currentPoint.Y - _anchorPoint.Y);
           RenderTransform = _transform;
           _anchorPoint = _currentPoint;
       }

       private void root_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
       {
           if (!_isInDrag) return;
           var element = sender as FrameworkElement;
           if (element != null) element.ReleaseMouseCapture();
           _isInDrag = false;
           e.Handled = true;
       }
