用戶控制從3.7遷移到5.2後停止工作

Question

我最近將我的3.7 sp4項目遷移到了5.2，但我在這樣做時遇到了問題。 目前，我的用戶控件在5.2項目中遷移後無法使用。

下面是代碼：

用戶控制編碼：

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="SiteMenu.ascx.cs" Inherits="UserControls_Nav_SiteMenu" %> 
<%@ Register TagPrefix="telerik" Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" %> 

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" /> 
<telerik:RadMenu ID="RadMenu1" runat="server" DataSourceID="SitemapDataSource1" OnItemDataBound="RadMenu1_ItemDataBound"> 
</telerik:RadMenu> 

用戶控件的類代碼：

但我在我的代碼搜索，你可以看到上面只有DataSourceID被定義。

我該怎麼辦？

謝謝

此值將在.aspx頁面的HTML中，而不是在後面的代碼中。在那裏查看，在Telerik RadControls版本遷移之前，我看到過這個問題。
