The simple solution is to split your grid: right-click on it in design mode, select Edit and click-drag from left-bottom corner. Maybe it will be satisfactory for your users? Another way is complicated and will require some code to reset ColumnOrder property for all columns in run-time when user navigates the grid, i.e. it may involve grid's scrolled and afterrocolchange events, column's relativecolumn and activecolumn properties.
