ASP.NET Menu and IE8 rendering white issue
If you are using the ASP.NET Menu control, you might encounter under certain circumstances an issue where the menu appears as a white box in IE8 Standards Mode.
What IE8 is doing IS correct (by design), in the sense that in Standards mode IE8 is following the standards. Specifically, (element).currentStyle.zIndex returns "auto" in Standards mode when zindex has not been set. The ASP.NET Menu control assumes a different value.
I’d like to suggest a few possible workarounds to solve quickly the issue (note, you can use either one of them, depending on your scenario):
Overriding the z-index property

在Asp.Net提供了三种常用的验证方式：Windows方式是和IIS结合起来可以实现基本、摘要、集成 Windows等身份验证；Passport方式是使用Windows Live ID的帐户来进行统一验证的；Forms方式是使用常见的表单来实现验证。
一、普通实现方式
这种方式是最简单的，只需要配置一下就可以了。
1、执行aspnet_regsql命令建立数据库
aspnet_regsql命令在C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727目录下，按提示运行就可以了
2、新建一个web网站
在Web.Config中加入配置：
<connectionStrings>
<add name="MySqlConnection" connectionString="Data Source=dbserver;Initial Catalog=database;user id=userid;password=****;" />
</connectionStrings>
<system.web>
