Hi
I have an ultragrid which I allow group by on. I also allow updating, deleting and inserting which gives me a null reference error. I'm not sure why and I've considered disabling the buttons on the group by event which I was able to do (example a). But when the group by is turned off how is there a better way to trap that?
Is it common practive to NOT allow Insert/Update/Delete when grouping? If so, Is there a better way to disable it?
