Description

Hi guys, In this Pagination api method below

getTotalPages: function () { if (!grid.options.enablePagination) { return null; } if (grid.options.useCustomPagination) { return grid.options.paginationPageSizes.length; } return (grid.options.totalItems === 0) ? 1 : Math.ceil(grid.options.totalItems / grid.options.paginationPageSize); }

in this part:

if (grid.options.useCustomPagination) { return grid.options.paginationPageSizes.length; }

It brokes the pagination, since it will never return the real quantity of pages to use, but the quantity in the pageSizes array ....

Contributor guide

Research direction
Inspect the getTotalPages() function in the pagination service. The custom pagination case incorrectly returns the length of paginationPageSizes array. The correct implementation should calculate the total pages based on the custom pagination logic, likely using totalItems and page size or similar properties.
