Thank you for your reply. In this case I am talking about when I close the form I am developing and then close VFP is when the issue occurs.

Either the next day or on my other computer I transport the data to during the day, when I start VFP and open the form to continue development, the rowsource property in each column of the grid is back to "None". The rowsource property for the grid itself still retains the correct rowsource name. Only the columns forget the property name.

Thanks again,

Gary
