我可以让rootmenuitemlefthtml和rootmenuitemrighthtml发出但不能发出分隔符。尝试了CDATA包装和设置SeparatorCssClass。我只想要根菜单项之间的管道。

<dnn:SOLPARTMENU runat="server" id="dnnSOLPARTMENU" Separator="<![CDATA[|]]>" SeparatorCssClass="MainMenu_SeparatorCSS"
        usearrows="false" 
        userootbreadcrumbarrow="false" usesubmenubreadcrumbarrow="false"
        rootmenuitemlefthtml=" &lt;span&gt;   " rootmenuitemrighthtml="   &lt;/span&gt;" rootmenuitemcssclass="rootmenuitem"
        rootmenuitemselectedcssclass="rootmenuitemselected" rootmenuitembreadcrumbcssclass="rootmenuitembreadcrumb"
        submenucssclass="submenu" submenuitemselectedcssclass="submenuitemselected" submenuitembreadcrumbcssclass="submenuitembreadcrumb"
        CSSNodeSelectedRoot="rootmenuitembreadcrumb" CSSNodeSelectedSub="submenuitembreadcrumb"
        MouseOverAction="False" MouseOutHideDelay="0"
        delaysubmenuload="true" level="Root" />

解决方案

虽然不是直接答案，但我们可能希望转到DotNetNuke菜单，而不是使用SolPart。 SolPart不再得到正式支持，并且此菜单的开发工作已在大约两年前停止。 SolPart的作者Jon Henning从头开始编写了DotNetNuke菜单，并试图解决原始SolPart菜单中的许多缺点。

检查此Solpartmenu：

    ClearDefaults="True" MenuBarCssClass="Hmain_dnnmenu_bar" MenuContainerCssClass="Hmain_dnnmenu_container"

    SubMenuCssClass="Hmain_dnnmenu_submenu" SubMenuItemSelectedCssClass="Hmain_dnnmenu_subselected"
    CSSNodeSelectedRoot="Hmain_dnnmenu_rootselected" MenuEffectsMouseOverDisplay="None"
    Separator="|" SeparatorCssClass="Hmain_dnnmenu_separator" UseArrows="False" UseRootBreadCrumbArrow="False" />
