We recently added row group functionality to our grids and we and our users are very happy with this. Only thing that bothers us is the drop functionality on the grouppanel. We an issues to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns. The drop marker indicated the new column to group will be added in front, but the column is added to the end of the grouped columns.
