Hi Nishant Session v/s Viewstate is quite a good question, but you need to consider two things before you make up your mind. 1. How long you want to retain the DataTable in Memory. i.e. if your site is hosted on shared server then you cannot hold it for more than a 5-10 mins as the services restart and the session is destroyed. So in this case the viewstate is better option. But if you are having dedicated server then opt for session. 2. Why not XML. Create a XML of datatable with unique name, write it to disk and then save the file name in ViewState. You will save both the ViewState and session memory.

Thanx Navaneeth, Got your point ,
