Hello ...
I have list view connected with timer to update values in list view  using ajax manager
when use
Rebind() it update all values in list view and reload images even if it not changed
How can i update just changed values 
Or Update some value

Hi Alharith,

In case you are updating values on a specific time frame using TimerTick event there is no option to determine which item which is entered in edit mode finishes its update in order to update it in the DataBase. It is expected to send the new data no matter if the user finishes the updater to the DB. This is the behavior of all DataBind controls.
