Hello everyone,
This feature is now available and it offers a lot more than saving and loading the current state (layout) of the grid. You can read more about how it works and what it provides in the documentation (https://docs.telerik.com/blazor-ui/components/grid/state) and also check it out live in the demos (https://demos.telerik.com/blazor-ui/grid/persist-state).
Regards,
