Hi
Upto now, i had understand that while using update panel in asp.net web form, it will increase the performance by using Asynchronous calls and minimum data transfer to server
and it will most suitable while using heavy control in webform like gridview or datalist with edit,delete functionalities.
But today while doing discussion with friends, they were telling there will be no minimum data transerfer from client to server, it will send full html data with viewstate to sever so there is no advantage related with bandwidth, it will only avoid the page full postback.
Could you tell me, which one is the correct ?
