I need to call parent form but my parent form is a listpage form. As I know I can't add new methods to list page forms i need to add this method to the interaction class of related list page form. But I do not have an idea how to do it.
Would you have any suggestion for me?
You have two options:
AutoRefreshData
on the menu item on the list page. This will refresh the list page, I am not sure when (maybe it works best on action menu items).element.args().record().datasource().research(true);
from the child form.
