.Net4.0 ASP Menu Control's StaticHoverStyle Unrendered

It has confused me for several days. No matter how hard I rewrite the codes, it seems never compassionate to me.

Google it as "No show asp:Menu StaticHoversSyle", still can't get appropriate answers.

Fortunately at last, Google it with the key word ".Not4.0". I got it.

It should be a bug. The styles can be work only when the menu control's "RenderingMode" property has been set as "Table".

Example codes:

<asp:Menu ID="Menu1" RenderingMode="Table" ...>

<StaticHoverStyle CssClass="staticMenuhover" />

...

</asp:Menu>
