推荐答案

使用Firebug（Firefox扩展）或类似的检查你的菜单的Z-指数东西。然后设置ModalPopupExtender的Z-1指数高。

Use Firebug(Firefox Extension) or something similar to inspect the Z-Index of your menu. Then set the ModalPopupExtender's Z-Index 1 higher.

在没有看到现场直播的页面，我无法猜测的z索引，但它必须大于100，您可以尝试将其设置为10001什么似地高。

Without seeing a live page, I can't guess the z-index, but it must be greater than 100. You can try setting it to 10001 or something wildly high.
