Jay, We are experiencing the same ideas here. We store column ordering and widths on the server but we have no way of getting events in the UI to know when changes have been complete.
wouldn't it be nice that the dnd was included as well, I could really use the DND of columns! Was it hard to implement ? We did not yet bother to investigate since we have to focus on getting functionality complete first.
