I added the lReadOnly property to a checkbox class and placed the control in the grid, setting the lReadOnly to .T. -- with the same results as before. All data disappears on the grid [in all columns] when I click on the header to resort. The checkbox column is the only one that "beeps" when you click on the checkbox in the grid. Nothing happens when you click on the other columns. Thanks for the suggestion -- any other ideas?

Thanks again,
Doug
