LoadContentFile does not work with inherited RadMenu

PROBLEM

LoadContentFile does not work with inherited RadMenu.

SOLUTION

The RadMenu for ASP.NET Ajax uses the built-in .NET XML serialization, which relies on the XmlRoot attribute. If your custom class does not have this attribute, an exception will occur. You should modify your source like:

C#

using Telerik.Web.UI;
using System.Xml.Serialization;

namespace Tuldi
{
    [XmlRoot("Menu")]
    public class customMenu : RadMenu
    {
    }
}

VB

Imports Telerik.Web.UI 
Imports System.Xml.Serialization 
 
Namespace Tuldi 
 
    <XmlRoot("Menu")> _ 
    Public Class customMenu 
        Inherits RadMenu 
    End Class 
End Namespace
