Hello Saurabh,

I revised the provided code and noticed that you do not have DataSource Control assigned in the markup as well as no handler for the NeedDataSource exists.
Therefore I would conclude that you are suing simple data binding by assigning DataSource for the RadGrid in the PageLoad event.
Note that if this is your scenario, simple data-binding mechanism is not supported with most of the RadGrid operations like paging, filtering, sorting, insert/update/delete ect.
Therefore please try implementing advanced data-binding as shown in the help topic below and see of this helps:
