问题描述
我在项目的启动页面中使用了4个Modalpopupextender。当我运行启动页面时，即使在单击指定的TargetControlID之前，我在Modalpopupextender中的PopupControlID下设置的面板也是可见的。我试图将那些可见的设置为false，但它有助于我，我还尝试创建一个css类来在加载页面时隐藏面板，并在单击指定按钮时查看面板但它既没有帮助我。请帮忙。谢谢。
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.
