automatic suggestion in grid

hello,

i have a case like this:

after i type a Sales Unit ID in smmSalesUnit , system will give a suggestion of its parent id. the suggested parent id should automatically filled in the next column in grid but the user still can edit the value(and the column is lookup to the emplTable)

how can i do that?

i’ve tried to fill the column automatically with a method, but changing the properties DataMethod will make the DataField properties being disabled and the lookup is not running

can somebody help me? i’ll be really thankful :’)

sorry for the awful english

use edit. or smmSalesUnit_ds.object(…).value(…)
