Hello Chamara ,

Go through the following help article which explains how to maintain CheckBox state on rebind.
Persisting CheckBox control state in GridTemplateColumn on rebind

You can also refer the following help article which explains how to maintain selected rows on paging.
Persisting the selected rows on sorting/paging/filtering/grouping
