I have two seemingly identical TcxGrids bound to two different tables. On one grid, when the column header is dragged and dropped to the group panel, a large X appears above the column being dragged, when it is dropped the column is immediately hidden. On the other grid a big circle with a line through it shows and it cannot be dropped on to the group panel. The Options.Grouping for both columns is false. Why the difference in the two behaviors ? I cannot see a property setting difference but I'm sure there must be one somewhere that causes this behavior. What property is it ?
