Re: Postback Still happening with UpdatePanel for Checkbox event inside item template - GridView

Great. Putting the whole grid in one UpdatePanel solved the above problem, but i for the gridview paging i need postback, which is not happening. I tried using Postback Trigger, but it doesnt have EventName property. :-( So what should i do? Any workarounds? Thanks.
