Hi Atif,

Please let us know how you populated your RadGrid. I suggest you consider adding a NeedDataSource handler and bind the control inside this handler.

More information about NeedDataSource:
Advanced data-binding w/NeedDataSource

Additionally, verify that the RadGrid control is added to Page's controls collection before exporting.

Let us know if you need further assistance.

Greetings,
Pavlina
