c# - On PostBackUrl property of a button, send only specific control instead of all controls to the previous page of destination page -

the question simple, when use postbackurl property source page , go destination page, on destination page, can access controls of source page on destination page using previouspage property.

my question is: possible send specific control instead of controls source page destination page. core purpose optimization. source page has more 300 controls. want send 1 specific control instead of 300 controls destination page, possible? thanx in advance. appreciated.

regards

are using ajax ?

i think should google viewstate, partial postbacks , updatepanels.

take here too: what partial postback?
