推荐答案

VirtualPathUtility.ToAbsolute("~/ProductsList.aspx?CategoryId=" + Eval("CategoryID")) %>"><%# Eval("CategoryName")

听起来在形成URL时存在问题.当前，所形成的URL不正确，因此当您尝试移动到该URL时，找不到页面，并且出现404错误.

尝试此技巧以获取正确的URL:解析多路径-Folder WebSite [ ^ ]

目前，URL似乎正在尝试在根文件夹中找到"ProductsList.aspx".一次，尝试将其移到那里并查看它.

Sounds like there is an issue in forming the URL. Currently, the URL formed is incorrect and thus when you try to move to that URL, no page is found and you get a 404 error.

Try this tip to get the correct URL: Resolving Paths in a Multi-Folder WebSite[^]

For now, it looks like the URL is trying to find the ''ProductsList.aspx'' in the root folder. For once, try moving it there and see it.
