Hello Sir,

i have created a small table which contains only name of cities.
On form level i want to create a dynamic list of the name of these cities just by clicking on the textbox without doing any hardcoding. Can anyone help me out in doing this.

Thank you.

Why not use an LOV? Alternatively see this thread

Hi,

First change the item type to list item
and create WHEN-NEW-BLOCK-INSTANCE trigger and write the fallowing code..

declare
cursor c is select name from cities;
cnt number:= 1;
begin
for i in c loop
add_list_elements('item_name',cnt,i.name,i.name);
cnt := cnt + 1;
end loop;
end;

Regards,
Siva

I'd put it in when-new-form-instance personally. If you've got a multi-block form you don't want that code running more than once.

NO, create the WHEN-NEW-BLOCK-INSTANCE trigger for the particular block which you want to create dynamic list item, then it will fire only for that block.
Don't create it in form level.

Huh? What exact problem do you think will occur if the code is at form level?

As you told, if it is created in form level it will fire morethan once for each block.

No it won't. I'm not sure why you think otherwise.

I wrote this code on WHEN-NEW-BLOCK-INSTANCE trigger

declare
cursor c is select name from cities;
cnt number:= 1;
begin
for i in c loop
add_list_elements('item_name',cnt,i.name,i.name);
cnt := cnt + 1;
end loop;
end;

but its giving error that add_list_elements should be declared.
how can i get rid of it.

Maybe because there's no such built-in? It is ADD_LIST_ELEMENT (singular, not plural - ELEMENTS).

yes sir, its add_list_element.

but again i am getting FRM-30351: No list elements defined for list item.
List ITEM_NAME.
here i dont want to define elements manually in list item. It should generate dynamically in that list from database.
what can i do on this.

Use messages to check if the query is returning data. And put the code in when-new-form-instance where it belongs. sivaora is wrong to suggest otherwise.

I wrote the same code in when-new-form-instance, but again its throwing the same error (identifier 'add_list_elements' must be declared). Can you please suggest me any alternate way.

Are you seriously telling us you can't work out why you're getting that error?
When Littlefoot already told you?
And you fixed it?

I don't believe you.
You may be getting a different error.
Post a screenshot showing the error message.

I wrote this code for generating dynamic list

declare
cursor c is select city_name from cities;
cnt number:= 1;
begin
for i in c loop
add_list_element('city_name',cnt,i.city_name);
cnt := cnt + 1;
end loop;
end;

and when i compiled i got error as : wrong number or types of arguments in call to 'ADD LIST ELEMENT'

ADD_LIST_ELEMENT expects 4 arguments - you provided 3. Read the documentation.

And you were passing 4 arguments before. You need to pay more attention to what you are doing.

Extremely sorry sir. I oversighted it. I rectified my mistake and now its getting compiled properly without any errors.
But during run time, the elements in list are not populating. Its giving: Invalid record group for list population.
Do i have to make a record group manualy for this?

You're getting FRM-41334 now? with that code?
Are you sure that's the correct error message?
Are you sure it's add_list_element that is causing the error?

Add_list_element doesn't use record groups so I don't see how you can get that error with that code.

Actually i just created a record group manually and because of that this error was comming. but now i deleted the record group and just ran the form with this code. Its not giving any error, but the list is not getting populated with elements.
