I'm sorry but we cannot really do anything with this. If we don't know property settings, code used, user action on the grid, there is not really a way to tell what is wrong.
Most obvious reason for this is that you use in your code something like
grid.Row := newrow and this newrow value is not within the 0..grid.RowCount - 1 boundaries.
