I recently Migrated my 3.7 sp4 project to 5.2, but I had issues while doing so.
Currently, my user controls are not working after migration in 5.2 project.
Below is the code:
User Control Code:
<%@ 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>
User Control's Class code:

{
}
protected override void Render(HtmlTextWriter writer)
{
// Checks if this is called by the Search Indexer and does not render anything if so.
// Navigation controls are present in every page and should NOT be indexed multiple times.
if (!CmsContext.IsRequestCrawler(this.Context))
base.Render(writer);
}

When I edit the Template(in Admin mode), the following error is displayed in control location:
Both DataSource and DataSourceID are defined on 'RadMenu1'. Remove one definition.

but I searched in my code as you can see above there's only DataSourceID is defined.
What should I do?
Thanks
