帮助在详细信息视图中使用文件上载
我正在尝试使用fileupload，在此页面上向gridview添加行。这个页面基本上是一个简单的管理面板，我可以将数据添加到我的数据库。文件上载用于获取文件的路径，并将路径上传到数据库而不是文件。问题是每当我运行我的程序选择一个文件，它上传很好，期望路径显示为真而不是路径。我真的很感谢帮助这是我的整个代码。 gridview和details视图都使用相同的sqladapater

您希望这样做的方式在最近的浏览器中不起作用 - 它们在您上传文件时不会发送完整的客户端路径信息。只有早期版本的Internet Explorer和其他一些版本才能执行此操作。
似乎有效的一种方法是使用Java applet来选择文件而不是本机文件上传小部件。由于您只需要文件的路径而不是实际文件本身，这是一个更好的解决方案（无需将文件上传到服务器）。
这是a link讨论和链接到这个工作的演示。请阅读评论。您将不得不查看演示页面的源代码（以及链接的js文件的来源），以了解如何使其工作。
如果该页面消失，我将复制以下相关链接：
