Insert Edit Update Delete in GridView using Client Object Model in SharePoint 2010



 
Note:-
  1. For Enabling SessionState in SharePoint 2010 I have followed the below link. http://www.kajanmoorthy.com/2010/05/enable-session-state-in-sharepoint-2010.html
  2. No Need to Use Session State or View State for this Example as you can need to touch DataBase while updation & Deletion. I just Tried show how to use session in SharePoint 2010.
