Storing datatable in ViewState is not a good practice as it increases the size of your page and reduces the performance, also ViewState can be deciphered on the client side, so the DataTable is not secure. You can do it through sessions or more better from Cache and if it is not being used frequently I suggest you to requery it from database. share|improve this answer answered May 30 '12 at 8:35 Imran Balouch 1,6681134 the issue is I want to do some modification on the Datatable that is why I want to keen a temp version, and I use a view state ti ensure it's removed when I leave a page –steve jobs May 30 '12 at 8:39 What are the values present in the datatable, if you store an unserializable object in a table, then the table is no more serilizable. you will need to write a serializer/deserialzer for each of your controls. –Imran Balouch May 30 '12 at 8:40 I think I found it :D, wrong data :D –steve jobs May 30 '12 at 9:05 Cheers, thats great –Imran Balouch May 30
