I am using 4 Modalpopupextender in my start-up page of my project. When I run my start-up page, the panels which I have set under PopupControlID in Modalpopupextender are visible even before the specified TargetControlID is clicked. I have tried to set visible of those to false but it dint helped me and I also tried to create a css class to hide a panel when page is loaded and to view the panel when specified button is clicked but it neither helped me. Please help. Thank you.

I have done this already. But this hides the panel when I run my startup page but it does not trigger when the specified button is clicked.
