我无法从我的头顶还记得,但我认为在这的XmlDataSource prevents你绑定到XML值中的错误节点。它与唯一的属性。如果我错了这个请大家指正。有你需要对你的XML文件略作修改:
I can't recall it from the top of my head but I think there was a bug in XmlDataSource that prevents you to bind to values of xml nodes. It works with attributes only. Please correct me if I am wrong with this. There's a slight modification you need to make to your XML file:
<%@ Page Language="C#" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string xml =
@"<?xml version=""1.0"" encoding=""utf-8"" ?>
<Databases>
<Database name=""foo"" />
<Database name=""bar"" />
<Database name=""baz"" />
</Databases>";
databasesSource.Data = xml;
databasesSource.DataBind();
}
}
</script>

<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:DropDownList ID="databases" runat="server" DataSourceID="databasesSource" DataValueField="name" DataTextField="name" />
<asp:XmlDataSource ID="databasesSource" runat="server" XPath="/Databases/Database" />
</div>
</form>
</body>
</html>
请注意,我加入的名称的属性,而不是直接使用节点的价值。
Note that I added the name attribute instead of using the value of the node directly.
如果您不能修改原始的XML文件的结构,你可以在其上使用应用XSLT转换的TransformFile财产在这个帖子描述。
If you can't modify the structure of your original XML file you can apply an XSLT transformation on it using the TransformFile property as described in this post.
