You need to use the DynamicCurrentControl event to refresh your column of pictures. We use a container which has an image control on it to give us the size control (stretch as you indicate). The container with empty image is the parent to all possibilities (images) that can be displayed. The DynamicCurrentControl is set to call a method in the grid which will evaluate your conditions and return the control with the appropriate image for display in the column.
Grid.Column1.DynamicCurrentControl = 'THIS.Parent.WhatPicture(Cursor.Value....)'
Works for us.
