>>>Exactly what I thought. And I am checking the ReadOnly property of the grid and it shows to be .T. But I can click and start making changes in any cell of the grid. I have some other forms in the application with grids and there it works as it is should; that is, you can click in a cell but not change anything. And I don't use AllowCellSelection in other forms. It must be something I am missing in my form. I will keep checking and testing.

The Grid ReadOnly doesn't mean cells readonly.

Check Column.ReadOnly values.
