I have created a data window which has a dropdown lit box for Gender. 

When a new record is added, the field shows display value to select from. However, when a window is retrieved, column shows data value instead of display value.

I did write below function in retrieveend event of datawindow. But it gives - "Invalid Arguments to Function" error. 

 

string ls_display

   ls_display = dw_sort.describe &
      ( "evaluate ( 'LookupDisplay ( dept_id )', " &
         + string ( dw_sort.GetRow() ) &
         + " )" )

Hi,

Can you please describe the problem a bit more extensive? I'm not sure what "gender" would have to do with "dept_id".
What do you mean with "When a new record is added, the field shows display value to select from. However, when a window is retrieved, column shows data value instead of display value.". Are you saying that when inserting a new row the dropdown is populated correctly, but when you open the window and show an already inserted row, the dddw does not populate?

Maybe some images?

Also, personally I always struggle with the "Evaluate" function. What I usually do, is add a computed column to the datawindow itself, which then uses the LookupDisplay(), much easier to use. From you powerbuilder script you can then do a GetItem...() on that computed column.

regards
