This sample demonstrates the Grid paging feature. In this sample, click the numeric items to navigate to particular page. You can also change the page size using the dropdown.
Paging allows you to display the contents of the Grid in page segments. By default, paging is disabled. To enable paging, set allowPaging property to true. pageSettings->pageSizes property enables a dropdown in pager which allows you to change the number of records in the Grid dynamically. In this demo, the Grid is rendered with pageSettings->pageSizes set to true and pageSettings->pageCount is set to 4. More information on the paging configuration can be found in this documentation section.
