QuestionDragDrop In A Canvas Pin

I'm trying to drag a user control around a canvas. I want to prevent the user from dragging the control outside the canvas.. See my comment in green.
private void Control_MouseMove(object sender, MouseEventArgs e)
{
    var draggableControl = sender as UserControl;

    if (isDragging && draggableControl != null)
    {
        Point currentPosition = e.GetPosition(this.Parent as UIElement);

        var transform = draggableControl.RenderTransform as TranslateTransform;
        if (transform == null)
        {
            transform = new TranslateTransform();
            draggableControl.RenderTransform = transform;
        }

        // Problem: currentPosition is the distance from the window's Left edge, 
        // not the left edge of the canvas
        var newX = currentPosition.X - clickPosition.X; 
        if (newX < 0)
        {
            newX = 0;
        }
        if (newX > parent.ActualWidth)
        {
            newX = parent.Width - this.Width;
        }
        transform.X = newX;
        transform.Y = currentPosition.Y - clickPosition.Y;
    }
}
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
