HI,
my problem is : I have 2 update Panels in my page.
i had set the ChildrenAsTriger=true and updateMode=Conditional for both the panels.
but when i click on button of 1 panel, another panel is getting update too.
i am using UpdatePanelAnimationExtender on both panels and showing some animation while panel is getting updated. But when i click on a button which is child of one of the panel, the other panel also shows the animation. i dont know what to do. Please help.
