Description

The Telerik UI for ASP.NET Core Grid provides a group-paging feature, which allows you to page through groups and load the group items on demand. The loading of group items is executed when a group is expanded. Group paging works with both local and remote data.

This demo presents a remotely-bound Data Grid with virtualization and enabled group paging functionality.
