What do u mean by "whenever needed have to take data from grid view"? If you wish to retrieve the changed values, it can be done in the RowUpdating event only and if you do not wish to store the data in a session, then you'll have to fetch the data from the database every time which would hamper your applications performance.
If you do not want to store the data source in the session and do anything manually, you can bind c1gridview to an AccessDataSource or a SqlDataSource and all operations would be handled automatically.
Let me know if you have any other questions.
