PowerBuilder – Getting the Display Value from a Drop Down DataWindow
This is very basic functionality but easily forgotten. Say you have a datawindow built from the ‘part’ table and a column for partType is a DDDW. You want the description of the partType code (which is displayed in the row showing the parts). To do this you use the evaluate method with the describe method on the datawindow.
string ls_desc
ls_desc = dw_parts.describe("evaluate('lookupdisplay(partTypeID)'," + string(ll_row))
Where ‘ll_row’ is the row number in dw_parts datawindow from which you want the description.
