Hi,
I suppose that you should use:

    elm_genlist_realized_items_update  (obj);

to update the content of all realized items in list. All CBs functions will be  called again to get the content, text and states.

I solved this problem, 

by using elm_genlist_clear() and reload all items.

thank you :)

why refresh the list though? if a specific item has updated (the data backing it has) then just update that item. do it for any items that update whenever needed.

when I create a item, it does not go into genlist directly, but go into my database first.

and my genlist gets updated items from the database.

so... I thought that it needs refresh button,

but now solved!!

thank you :)

Hi, 

Good example is in IDE sample, create UI controls demo, then find the genlist in it. Maybe that will be helpful to understand genlist.

update the whole genlist will cause performance issue if it has very much items, especially the item has icon image.

a better way is just to update the specific item if needed.

such as:

Elm_Object_Item *it = elm_genlist_nth_item_get(genlistObj, 2);
elm_genlist_item_fields_update(it, "elm.swallow.icon", ELM_GENLIST_ITEM_FIELD_CONTENT);

vikram is totally right - just update the items that need updating. if you really want then only update items that have been realized.
