SiteMapPath：更改链中最后一个链接的标题和链接

你好你能建议任何解决方案吗？我有一个 SiteMapPath 控件，而不是像

Home > Accounts > User Account

“用户帐户”指的是 ~/UserAccount.aspx

这样的默认功能，我想覆盖最后一个节点以显示有关当前用户的信息，即：

Home > Accounts > John White

“John White”指的是 ~/ UserAccount.aspx?id=111 ？

Hi
Can you advise please any solution?
I have a SiteMapPath control and instead of default functionality like

Home > Accounts > User Account

where "User Account" refers to ~/UserAccount.aspx

I would like to overwrite the last node to show info about a current user, i.e.:

Home > Accounts > John White

and "John White" refers to ~/UserAccount.aspx?id=111 ?

是的，您必须继承 XmlSiteMapProvider 并重写其 BuildSiteMap 方法。在这里，您可以在运行时操作您想要的任何节点，这些节点随后将显示在您的 SiteMapPath 控件中。

public class MySiteMapProvider : XmlSiteMapProvider
{
   ...

   public override SiteMapNode BuildSiteMap()
   {
     var node = base.BuildSiteMap();
     var userAccountsNode = this.FindUserAccountsNode(node);

     userAccountsNode.ReadOnly = false;
     userAccountsNode.Title = ...;
     userAccountsNode.Url = ...;
     userAccountsNode.ReadOnly = true;

     return node;
   }
}

Yeah, you have to inherit from the XmlSiteMapProvider and override its BuildSiteMap method. In here you can manipulate any nodes you want at runtime, which will then show up in your SiteMapPath control.

public class MySiteMapProvider : XmlSiteMapProvider
{
   ...

   public override SiteMapNode BuildSiteMap()
   {
     var node = base.BuildSiteMap();
     var userAccountsNode = this.FindUserAccountsNode(node);

     userAccountsNode.ReadOnly = false;
     userAccountsNode.Title = ...;
     userAccountsNode.Url = ...;
     userAccountsNode.ReadOnly = true;

     return node;
   }
}
