Hi Idriss, sorry for not responding earlier. For some reason I haven't received a new answer email notification. Regarding your two questions. 1) Currently I don't have a sample for that ready to publish but I'll be creating one the next few days as I have received numerous requests for it. 2) Like with the standard DataGrid the columns collection is only filled when AutoGenerateColumn is set to false. So please make sure you change that accordingly. HTH Denis
