Dear friend Hope u are doing goodin order to replicate the above mentioned issue You need to understand the basic diffrence between synchronus and asynchronus calls : AsyncPostBackTrigger: Asynchronous Postback triggers update the page partially without refreshing the whole page (AJAX) -Converts postbacks into async callbacks -Typically used to trigger updates when controls outside an UpdatePanel post back If ChildrenAsTriggers=false can be used to specify which controls inside UpdatePanel should call back rather than post-back PostBackTrigger: Postback triggers update the complete page caused by complete post of the page to the server. -Lets controls inside UpdatePanel post back -Typically used to allow certain controls to post back when ChildrenAsTriggers=true the above understanding will clarify u how the data get posted twiceuse synchronous calls will not affect perfomance and server side caching can be avoided using itso best shot was to go with Synchronous calls Hope it helpsfeel free to revert me back if u face any issues Cheers! Happy coding
