Google Chrome 不兼容ASP.NET Menu!
问题：1. CSS没有正常应用 2. 鼠标点击事件postback有误 3. 下拉子目录不能显示
更新：使用ASP.NET 2.0 CSS Friendly Control Adapters可以解决
今天有客户反馈说他网站的ASP.NET Menu在Google Chrome 下竟不能正常显示，我简单试了一下，果然有问题！
问题：
1. CSS没有正常应用
2. 鼠标点击事件有误
3. 下拉子目录不能显示
虽然说Google Chrome 还在测试，但市场占有率也绝非一般杂牌浏览器能够相比的，与ASP.NET有这样的兼容性问题也确实不容小觑，希望有应用了menu控件的兄弟们做好心理准备.
试验代码如下（在IE各版本和Firefox3.0下均正常，截图在页面底部）：

当然ASP.NET 本身render出来的代码就不好，我会去试一下CSS friendly adapter生成的menu，看是不是还有问题...

使用了CSS Friendly Control Adapter的情况下，简单的menu和有模板节点的menu在Chrome下一切正常！
render出来的Markup如下：
