Consider a Grid DataWindow with FIELDS, A & B.
Both the fields are with edit style Drop Down Datawindow.
The Data Value is different from the Display value for FIELD B DDDW.
The FIELD B DDDW, retrieves based on the value entred in the FIELD A.
Suppose the FIELD A DDDW has two values: a, b
Corresponding Data (Display) values in the FIELD B DDDW are:
The first row in the grid is saved with the value 'a' for the FIELD A and '1' for the FIELD B. The Field B displays the display value i.e ONE.
Now another row is saved with the value 'b' forthe field 'A' and '3' for the field 'B'. The field B in the first row now displays '1' instead of 'ONE'
