在 asp.net 中动态构建的 SiteMapPath [英] Dynamically built SiteMapPath in asp.net

问题描述

我正在尝试使用 SiteMapPath 在我的网站上构建动态站点地图.

I'm trying to build a dynamic site map on my site using SiteMapPath.

应该是这样的:

Home > Products > %product_name% > Prices

其中 %product_name% 是在运行时动态设置的，具体取决于用户的选择.

where %product_name% is set dynamically in the runtime, depending on the user's choice.

我已经阅读了很多关于该主题的文章并选择了这个http://harriyott.com/2007/03/adding-dynamic-nodes-to-aspnet-site.aspx.它动态更改 web.sitemap XML 文件.问题是它仍然在开始时只构建站点地图一次，然后在每个页面上使用它.

I've read many articles on the theme and choose this http://harriyott.com/2007/03/adding-dynamic-nodes-to-aspnet-site.aspx. It dynamically changes the web.sitemap XML file. The problem is that it still builds the sitemap only once in the beginning and then uses it on each page.

我怎样才能让它在每个加载的页面上重建?

How can I make it to rebuild on each loaded page?

推荐答案

试试这个:

右键单击您的项目添加新项目"，然后选择站点地图"，它将具有如下所示的 XML 结构:

Right click on your project "add new item" then choose "Site Map", it will have an XML structure that looks like:

<?xml version="1.0" encoding="utf-8" ?>

     <siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >

       <siteMapNode url="~/Default.aspx" title="Home " description="">

         <siteMapNode url="~/the page URL" title="Products"  description="" >

             <siteMapNode url="~/the page URL" title=" %product_name%"  description="" >

                 <siteMapNode url="~/the page URL" title="Prices"  description="" />

             </siteMapNode >

         </siteMapNode >

       </siteMapNode >

     <sitemap>

** 为每个节点添加描述是可选的.

** adding description for each node is optional.

现在你需要把它放在你想要的地方，所以你在页面的 HTML 端添加这段代码:

Now you need to place it where you want, so you add this code in the HTML side of the page:

<asp:SiteMapPath ID="SiteMapPath1" runat="server">

<CurrentNodeStyle CssClass="Some class" />

   <PathSeparatorTemplate>

      <img runat="server" alt="" src="an image to separate between nodes" height="5" width="5" />

   </PathSeparatorTemplate>

</asp:SiteMapPath>

当然，您有两页 - 一页是产品，一页是价格.

---

Of course you have two pages - one for product and one for prices.

为 SiteMap 中的某个节点动态分配 Tile；在价格页面中添加此代码:

To assign Tile dynamically for some node in the SiteMap; add this code in the Prices Page:

1) 在页面加载中:

SiteMap.SiteMapResolve += new SiteMapResolveEventHandler(SiteMap_SiteMapResolve);

2)在同一页面(价格页面)添加此功能:

2) Add this function in the same page (prices page):

 SiteMapNode SiteMap_SiteMapResolve(object sender, SiteMapResolveEventArgs e)
{
    SiteMapNode currentNode = SiteMap.CurrentNode.Clone(true);
    SiteMapNode tempNode = currentNode;

    tempNode.ParentNode.Title = "Change the Product name";
    tempNode.ParentNode.Url = "Change the Product url";

    return currentNode;
}

如您所见，您可以根据需要操作父节点，更改标题、url 等.我认为您也想更改 url；例如:product.aspx?ID=blah"

As you can see you can manipulate the parent Node as you want, change the title, the url, etc. I think you want to change the url too; for example: "product.aspx?ID=blah"
