The order in which persistent field components are listed in the Fields editor list box is the default order in which the fields appear in a data-aware grid component. You can change field order by dragging and dropping fields in the list box.

1. Select the fields. You can select and order one or more fields at a time.
2. Drag the fields to a new location.

If you select a noncontiguous set of fields and drag them to a new location, they are inserted as a contiguous block. Within the block, the order of fields does not change. 

Alternatively, you can select the field, and use Ctrl+Up and Ctrl+Dn to change an individual field's order in the list.
