用户控制从3.7迁移到5.2后停止工作

Question

我最近将我的3.7 sp4项目迁移到了5.2，但我在这样做时遇到了问题。 目前，我的用户控件在5.2项目中迁移后无法使用。

下面是代码：

用户控制编码：

<%@ 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> 

用户控件的类代码：

但我在我的代码搜索，你可以看到上面只有DataSourceID被定义。

我该怎么办？

谢谢

此值将在.aspx页面的HTML中，而不是在后面的代码中。在那里查看，在Telerik RadControls版本迁移之前，我看到过这个问题。
