Our testing team reported that on occasion column reordering by drag-and-drop resulted in other columns moving. Since we do not implement any custom reordering or drag-and-drop functionality in the grid, I could not figure out why this was happening. Therefore, I added event handlers for ColumnReordering and ColumnReordered. What I discovered was that sometimes the events were being called multiple times for a single drag-drop operation on a column. This was happening in a somewhat random pattern. I could drag a column to a new position, and it would work ok with the events only called once, then I would drag another column, and three columns would move to new positions, with the event called for each move.
Right now, we are using version 2011.1.419.40. Are there any known issues with column reordering that were fixed?
Thanks for your help.
