How to count pages in main.ui.grid navigation?

Question

1C-Bitrix

Colleagues, I want to use the Bitrix grid in public.
Data in ORM, output.
I pass NAV_OBJECT to the grid, formed as follows:

$grid_options = new Bitrix\Main\Grid\Options('my_list');
        $sort = $grid_options->GetSorting(['sort' => ['NAME' => 'DESC'], 'vars' => ['by' => 'by', 'order' => 'order']]);

        $nav_params = $grid_options->GetNavParams();

        $nav = new Bitrix\Main\UI\PageNavigation('my_list_nav');
        $nav->allowAllRecords(true)
            ->setPageSize($nav_params['nPageSize'])
            ->initFromUri();

There is a navigation bar, but it does not count the page size. There is categorically little time to read the source code, can anyone come across? Help out)


Displays the selected amount, but does not paginate.


Here is the object itself, something seems to be missing here.

The answer is here

$nav->setRecordCount($controlsRes->getCount()); - it is necessary to set the total number of entries.
It was floating somewhere in the back of consciousness)
I was pleased with the documentation as usual) This method is not here.
