Hello Mehrdad,

RadGrid loses its current selection when the data is sorted, a new group or filter is added, or when the current page changes. If you want the client-side selection to persist across these events, please refer to the following article.
Persisting the selected rows client-side on sorting/paging/filtering/grouping.

Thanks,
Princy.
