If you are loading the grid from a BO, you could just serailize the contents of the BO and save it to disk...you could also just serialize the BO.  You can serialize the BO to disk or a Byte() array.  Here is another thread that I posted that shows how to do this: http://forum.strataframe.net/FindPost11884.aspx

I am looking to save a Grid Image Snap shot or a  DevExpress Report  to a database.  Has anybody have a sample on how to do this.  This would be greatly appreciated.
