Sorting, and extra rows appearing

Early in the development of my program when i double-clicked on a column header extra columns would appear such as the primary key and other unbound column fields. At that time I disabled sorting. Now I am reenabling it and everything seems to work fine. It seems odd and I dont like things fixing themselves without knowing why. Any idea why the extra columns would appear when the column headers are clicked on, and maybe I can figure out why they arent any more. Thanks, simon

Are you using the 2.0 beta code? Version 2010 had a problem with GridBoundColumns being reset on sorts. This was fixed in later versions.

thats very likely it. i switched versions at some point. thanks, good to know :)
