Well, it is difficult to detect what is true and what is not because you keep posting rubbish. Last statement you posted contains a comma character in front of the FROM keyword, so that wouldn't compile either. Once you decide to post real code you used in a form, someone might decide to try & assist.

Just wondering: why do you insist on dynamic approach? There's nothing "dynamic" in SELECT statement you use.

You have populated the data you need. The next step is displaying them correctly.
First define a node collection.
Later you can define the nodes that are contained in the node collection, this can be made dynamically
using a while statement.

@chrisvelarde - list items do not have nodes, you're thinkg of hierarchical trees
@irfankundi786@yahoo.com - are you getting an error?

I'm sorry, my fault. Didn't personally work on a list.

Nevertheless I assume there has to be an analogy between both OCX objects.

In the TreeView you use for example the command release_obj(hNode); in order to display a previously defined object
in the OCX container. Perhaps there is a similar function/procedure for the list.

It also isn't clear which EVENT triggers the code?

A first approach may be to know exactly which packages are being used by the list and have to be present.
The information you find in the Internet about this topic is very scarce. Had serious trouble figuring out
the architecture for the tree myself. A step by step analysis helped me to put all the missing parts together
until everything became to make sense.

Perhaps you have a data type problem. Your query returns two values and maybe you have to populate
every column in the list separately? Try displaying first only one column and one line to figure out
the logic behind it.

Dear,
Quote:

Declare
group_id recordgroup;
v_num number;
begin
group_id := create_group_from_query('lst','select (imt.item_id), to_char(imt.item_code) from items_mt imt');
v_num := Populate_group(group_id);
populate_list('lst_product',v_num);
End;



1- Create Procedure in the Forms Program Units.
PROCEDURE populate_Itms_group IS
  rg_name  VARCHAR2(50):= 'ITM';
  rg_id    RecordGroup; 
  errcode  number;
  list_value VARCHAR2(500);
BEGIN 
  rg_id:=Find_Group( rg_name ); 
 
  errcode := POPULATE_Group_WITH_Query( rg_id,'SELECT Item_id,  item_code FROM ITEMS_MT' );  
  clear_list('ITEMS_MT.ITEM_ID'); 
  -- Field Name where you put your List
  populate_list('ITEMS_MT.ITEM_ID',rg_id); 

EXCEPTION
WHEN OTHERS THEN 
MESSAGE('No Value ');
END; 


2- Call this WHEN-NEW-FORM-INSTANCE
populate_Itms_group ;

3- Go to Item Field where you want to put your Item List
Change his Item Type - List Item

4- Go to Elements in List click it and put there
List Elements - Dummy & List Item value - 0

Try this Hopefully it'll work.

Irfan

No there isn't.

That is a good question

None.

Probably because the form builder help topics on the subject are comprehensive.

No.

  IF NOT Id_Null(rg_id) THEN 
  	 Delete_Group( rg_id ); 
  END IF; 
  
  IF :RDG_VAL = 'E' 
  THEN
      rg_id := Create_Group_From_Query( rg_name, 'SELECT ename ename1,'

                                               ||'ORDER BY 1');
  END IF;                                              
  errcode := Populate_Group( rg_id ); 
  populate_List('TEST_LIST',rg_id);
END;
