动态建立的SiteMapPath在asp.net [英] Dynamically built SiteMapPath in asp.net

问题描述

我试图建立使用的SiteMapPath我的网站的动态站点地图。

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％动态设置在运行时，这取决于用户的选择。

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

我读过关于这一主题的许多文章，并选择这个的 http://harriyott.com/2007/03/adding-dynamic-nodes-to-aspnet-site.aspx 。它动态地改变了的web.sitemap XML文件。的问题是，它仍然在开始生成站点地图只有一次，然后使用它的每个页面上。

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.

我怎样才能让每一个加载页面上重建？

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

推荐答案

试试这个：

右键点击您的项目添加新项，然后选择网站地图
这将有一个XML结构如下：

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>

**增加了对每个节点的描述是可选的。

** adding description for each node is optional.

现在，您需要将它放在你想要的，让你在页面的HTML端添加此code：

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，你有两个页面 - 一个是产品，一个是价格

---

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

要在地图的某个节点动态分配瓷砖;在价格页面添加此code：

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

1）在页面加载速度：

1) In the page load:

SiteMap.SiteMapResolve += new SiteMapResolveEventHandler(SiteMap_SiteMapResolve);

2）在同一个页面（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;
}

正如你可以看到你可以操纵的父节点，只要你想，更改标题，URL等我想你想更改URL过;例如：product.aspx ID =胡说？

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"
