Asp.net 4 TreeView SelectedNodeStyle ImageUrl 似乎被忽略

我有以下代码，无论我尝试做什么，似乎 SelectedNodeStyle 上的 ImageUrl 都会被忽略。我是不是在做一些本末倒置的事情？

请注意，此线程是 ASP.带有 SiteMap 的 Net TreeView 忽略了 Node.Selected，它提出了一个不同的问题并揭示了这个新问题。

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
    <NodeStyle ForeColor="White" Font-Bold="true" NodeSpacing="5"
        HorizontalPadding="5" ImageUrl="~/Images/Page.png" />
    <SelectedNodeStyle Font-Bold="true" NodeSpacing="5" 
        HorizontalPadding="5" ImageUrl="~/Images/Page_Hot.png"/>
    <HoverNodeStyle ForeColor="Navy" />
</asp:TreeView>

在上面的示例中，所选节点下划线效果非常好。然而，形象永远不会改变。是的，我仔细检查了图像的命名是否正确。它改变了其他样式属性，但不改变图像。相当令人沮丧。

解决方案？

原文

I have the following code and no matter what I try to do, it seems the ImageUrl on the SelectedNodeStyle is ignored. Am I doing something backwards?

Note that this thread is a continuation of ASP.Net TreeView with SiteMap is ignoring Node.Selected which asked a different question and revealed this new question.

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
    <NodeStyle ForeColor="White" Font-Bold="true" NodeSpacing="5"
        HorizontalPadding="5" ImageUrl="~/Images/Page.png" />
    <SelectedNodeStyle Font-Bold="true" NodeSpacing="5" 
        HorizontalPadding="5" ImageUrl="~/Images/Page_Hot.png"/>
    <HoverNodeStyle ForeColor="Navy" />
</asp:TreeView>

In the sample above, the selected node underlining works just perfectly. However, the image never changes. Yes, I double-checked the image was named correctly. It changes the other style attributes, just not the image. Quite frustrating.

Solution?
