Dynamic drop down list in Adobe forms

Question

I have created a drop down list using enumerated drop down list from webdynpro native tab and binded in the object palette by giving $record.sap-vhlist.DESCR\.DATA\.FIELD.item[]* in the list items dynamically.DESCR is the field in the internal table into which i fetched data from the database table .I have written this code in a BADI.I dont know whether my form's display type is activex or native? I am not getting any values in the drop down list.can anybody please tell me what might be missing and how should i know whether my form is ActiveX or Native?
My form is called from portal so i have used BADI to connect portal to form

Hi sarang,
I have done a dynamic drop down list in which DESCR field comes from database table and pops into the drop down dynamically. I was working for a PCR scenario so the adobe form was called from portal.I will tell u all the required steps.It might work for u as it is working for me:
1.In the form:
I used two elements from library first is a "ENUMERATED DROP DOWN LIST NO SELECT" from web-dynpro native tab and second is "ISR_TEXT DISPLAY INVISIBLE ON EDIT MODE" from ISR controls tab.Place them one on other inthe form.
For drop down list the setting are:
     In object, field tab click on list items there in ITEMS put :$record.sap-vhlist.DESCR\.DATA\.FIELD.item[*].in ITEMS TEXT write text in ITEMS KEY write key.
     In binding,in default binding put $record.DESCR.DATA[*].FIELD.
For text element the settings are:
     In binding,default binding put Normal.
     when we select ISR_TEXT DISPLAY INVISIBLE ON EDIT MODE it automatically comes with calculated read only int he value tab.so open script editor and place the below code:
$record.DESCR.DATA.FIELD (in calculate).
2.Now the code in BADI is as follows:
In BADI we have to write the code for drop down list in the METHOD "SCENARIO_SET_ADDITIONAL_VALUES"
As i didnt change the standard BADI i added an enhancement spot in which i wrote a function module which fills ADDITIONAL_DATA. and the below code fills the ADDITIONAL_DATA .
DATA: t_t572b TYPE STANDARD TABLE OF t572b WITH HEADER LINE,
        t_t554t TYPE STANDARD TABLE OF t554t WITH HEADER LINE.
  SELECT * FROM t572b INTO TABLE t_t572b WHERE sprsl EQ 'E'.
  CLEAR ls_additional_data-fieldindex.
  LOOP AT t_t572b.
    ADD 1 TO ls_additional_data-fieldindex.
    ls_additional_data-fieldname ='DESCR_KEY'.
    ls_additional_data-fieldvalue = t_t572b-descd.
    APPEND ls_additional_data TO additional_data.
    ls_additional_data-fieldname ='DESCR_LABEL'.
    ls_additional_data-fieldvalue = t_t572b-descr.
    APPEND ls_additional_data TO additional_data.
    CLEAR t_t572b.
  ENDLOOP.
For DESCR field the we have to declare  DESCR_KEY and DESCR_LABEL in the place holders for key values and palce holders for default values in characteristics tab(where all the fields for the form are defined) of ur respective scenario.(where ur pcr scenario is defined)
Hope ur problem got resolved.
Please let me know if any doubts.
If ur form is not called from portal and u want a dynamic drop down list the difference is put a data drop down list and in object, field tab click on list items there in ITEMS select the field into which u populated the data from the database table (this code shud be written in code Initialization in the respective interface) and in ITEMS TEXT put $ in ITEMS KEY put $.and in binding as we normally do bind it to the respective field in which the data is populated from database table.
It should work.
