MOSS 2007中"快速启动"菜单的显示行为不一致
时间：2020-03-06 14:22:15 来源:igfitidea点击:
我试图将"快速启动"菜单配置为仅显示当前选择节点的祖先节点和后代节点。菜单还需要显示根节点的所有子节点。更简单地说：
给出以下站点地图：
根站点
--- SubSite1 =导航设置为"显示当前站点，当前站点下方的导航项以及当前站点的同级"
----- Heading1 =导航设置为"显示与父站点相同的导航项"
------- Page1 =导航设置为"显示与父站点相同的导航项"
------- Page2 =导航设置为"显示与父站点相同的导航项"
----- Heading2 =导航设置为"显示与父站点相同的导航项"
--- SubSite2 =导航设置为"显示当前站点，当前站点下方的导航项以及当前站点的同级"
----- Heading1 =导航设置为"显示与父站点相同的导航项"
SiteMapProvider配置：
<PublishingNavigation:PortalSiteMapDataSource ID="SiteMapDS" Runat="server" SiteMapProvider="CurrentNavSiteMapProvider" EnableViewState="true" StartFromCurrentNode="true" ShowStartingNode="false"/>
SubSite1上显示的"快速启动"菜单的预期行为和实际行为是：
--- SubSite1
-----标题1
-------第1页
- -第2页
-----标题2
--- SubSite2
导航到SubSite2的Heading1后，菜单的预期行为：
--- SubSite1
--- SubSite2
-----标题1
导航到SubSite2的Heading1后，我实际上看到的是：
--- SubSite1
-----标题1
-------第1页
- -第2页
-----标题2
--- SubSite2
-----标题1
如果将Heading1导航设置为"显示
我希望与父站点相同的导航项"和SubSite2设置为"显示当前站点，当前站点下方的导航项以及当前站点的同级"。
Heading1继承了SubSite2的导航项，而SubSite1项从视图中折叠了起来。我也玩过各种
修剪...没有成功的属性。任何帮助将不胜感激！
解决方案
我个人不喜欢默认菜单提供的html(基于表格的布局)。
幸运的是，SharePoint团队已经发布了该控件的代码。
我们要做的是将该代码包含在项目中，并且重写了render方法以执行我们想要的任何操作。这使我们可以灵活地定义需要显示的父级之间的确切关系，以及在创建的所有div上设置样式。
不利的一面是，我们现在正在编码，而不是进行配置，并且需要对用于使用控件的母版页进行更改。
我认为值得。现在，这是我们对任何站点进行的标准更改。
我按照@Nat的指导进入了模糊的世界Sharepoint Webparts，以实现我上面描述的行为。我的方法是发布自己通过Microsoft通过ECM团队博客发布的MossMenu Webpart版本。此代码基于本机AspMenu控件。我使用此控件来"拦截"通过标记中的DataSourceId属性注入的本地SiteMapDataSource，并创建一个新的XML数据源以展现所需的行为。在这个罗word的答案的结尾，我已经包含了最终的源代码。以下是母版页标记中的内容：
<%@ Register TagPrefix="myCustom" Namespace="YourCompany.CustomWebParts"
Assembly="YourCompany.CustomWebParts, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=9f4da00116c38ec5" %>
...
<myCustom:MossMenu ID="CurrentNav" runat="server" datasourceID="SiteMapDS"
orientation="Vertical" UseCompactMenus="true" StaticDisplayLevels="6"
MaximumDynamicDisplayLevels="0" StaticSubMenuIndent="5" ItemWrap="false"
AccessKey="3" CssClass="leftNav"
SkipLinkText="<%$Resources:cms,masterpages_skiplinktext%>">
<LevelMenuItemStyles>
<asp:MenuItemStyle CssClass="Nav" />
<asp:MenuItemStyle CssClass="SecNav" />
</LevelMenuItemStyles>
<StaticHoverStyle CssClass="leftNavHover"/>
<StaticSelectedStyle CssClass="leftNavSelected"/>
<DynamicMenuStyle CssClass="leftNavFlyOuts" />
<DynamicMenuItemStyle CssClass="leftNavFlyOutsItem"/>
<DynamicHoverStyle CssClass="leftNavFlyOutsHover"/>
</myCustom:MossMenu>
<PublishingNavigation:PortalSiteMapDataSource ID="SiteMapDS" Runat="server"
SiteMapProvider="CurrentNavSiteMapProvider" EnableViewState="true"
StartFromCurrentNode="true" ShowStartingNode="false"/>
...
我遵循了出色的分步说明，在MossMenu Webpart的注释部分中创建了自定义Web部件，网址为" Roel，2007年9月19日，星期三，7：20。在我的谷歌搜索中，我还发现了一些配置SharePoint网站的方法，以便通过在此处进行web.config更改来以类似于ASP.NET的可爱方式显示异常。
我决定将自定义行为称为"紧凑菜单"，因此在控件上创建了UseCompactMenus属性。如果未在标记中将此属性设置为true，则该控件的行为与AspMenu控件相同。
我的应用程序使用户始终从站点地图根目录的主页开始。当显示根页面时，我可以让自定义控件存储初始(完整)站点地图。它存储在静态字符串中以用于自定义行为。如果应用程序不遵循此假设，则该控件将无法按预期工作。
在初始应用程序页面上，菜单中仅显示到根页面的直接子页面。单击这些菜单节点将打开其下的所有子节点，但将兄弟节点保持"关闭"状态。如果单击其他同级节点之一，它将折叠当前节点并打开新选择的节点。就是这样，享受！！

我们用来实现我们想要的效果的方法是使用CSS Friendly Control Adapters。适配器可以更改呈现的HTML，而无需更改我们在页面上使用的控件。我们可能需要稍微调整菜单适配器以获取所需的布局。我们只花了几行代码。一旦工作正常，就可以使用CSS获得我们描述的行为。
