I'm in the process of styling an asp.net menu and I'm trying to understand the meaning of the StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass parameters.

My understanding is that the styles defined with these parameters are applied as CSS classes to the relevant elements, whenever needed. So I created my menu as follows:

<asp:Menu ID="NavigationMenu" DataSourceID="NavigationSiteMapDataSource" 
        StaticMenuStyle-CssClass="StaticMenuStyle"
        StaticMenuItemStyle-CssClass="StaticMenuItemStyle"
        StaticSelectedStyle-CssClass="StaticSelectedStyle"
        StaticHoverStyle-CssClass="StaticHoverStyle"
        Orientation="Horizontal" 
        MaximumDynamicDisplayLevels="0" 
        runat="server">
</asp:Menu>

It works for StaticMenuStyle-CssClass and StaticMenuStyle-CssClass (the classes are applied to the relevant elements), but StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass are not applied, regardless of the selected or hover status of an element.

What am I supposed to do to make this work?

Thanks.
