我在使用modalpopup扩展程序弹出的面板中使用日历扩展程序，因此面板加载包含日历扩展程序，但日历是每个东西的后面，我试图改变z-index但是一切都是徒劳的，似乎对我来说，它是ASP.net AjaxToolKit中的一个错误。任何人都对这个问题有所了解，是否可以解决？

日历扩展程序是ajax扩展程序还是指asp日历控件？无论哪种方式，我都在同样的情况下尝试了两种方式并且它有效。尝试发布您正在使用的一些代码，以便我们可以看到问题所在，并提供进一步的帮助。
编辑：这是我用你的代码。我取出了用户控件，所以我可以调试页面，它似乎工作。这是一个screenshot

适用于我的CSS解决方案：
.ajax__calendar_container
{
position :absolute;
z-index : 100003 !important;
}
请务必使用！important 声明。没有它，z-index总是被更高的设置所覆盖。您还应该在css中检查弹出对话框中的z-index及其背景。
