Hello Jhansi261984,
One possible way to achieve this functionality is to modify the Data Source itself and then rebind the grid like shown in the following article - http://help.infragistics.com/Help/NetAdvantage/ASPNET/2010.3/CLR4.0/html/WebGrid_Updating_Data_with_a_Data_Set.html
Let me know if this is the functionality that you require.
Let me know if you need further assistance.
