ScriptAttribute Problem

Hi,

 I'm having a problem with creating a ScriptableMember.  I added this code to my project:

 

using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Browser;
using Telerik.Windows.Controls;
using AMRSilverlight.AlchemySilverlight;
using AMRSilverlight.DataSources;
using System;

namespace AMRSilverlight
{
    public partial class MedDlg : UserControl
    {
        private bool changingValues = false;
        private bool loading = false;
        private string _ptGUID = String.Empty;
        private string _findMed = String.Empty;
        
        public MedDlg()
        {
            loading = true;

            InitializeComponent();

            Loaded += new RoutedEventHandler(MedDlg_Loaded);

            ...

            loading = false;
        }

        private void MedDlg_Loaded(object sender, RoutedEventArgs e)
        {
            HtmlPage.RegisterScriptableObject("MedDlg", this);
        }

        public MedDlg(string ptGUID, string findMed)
            : this()
        {
            _ptGUID = ptGUID;
            _findMed = findMed;
        }

        [ScriptableMember]
        public void Dummy(string dummy)
        {
            Console.WriteLine(dummy);
        }

        ...

    }
}

 I got a runtime exception about my object not having any scriptable members.  I rem'd out these lines

            Loaded += new RoutedEventHandler(MedDlg_Loaded);
             HtmlPage.RegisterScriptableObject("MedDlg", this);

         [ScriptableMember]
        public void Dummy(string dummy)
        {
            Console.WriteLine(dummy);
        }

and I still get the exception.  What am I doing wrong?

Thanks,

Darren

Very strange, this doesn't look like something is wrong. But then again, are you sure you did a rebuild and a refresh in the browser? Definitely looks like you're looking to old code. If this doesn't solve anything, can you post your complete solution somewhere? So I or other forum members can take a look at it? I think you want to communicate with the html, maybe there's something strange in there.

Thanks for your response!

 Yes, I cleaned the solution and rebuilt it.  Same result.  I duplicated the relevent portion of the code into a different project and it worked.  I can't even duplicate the problem in another project.

 

Could there be something something wrong with my ASPX?

  

<%@ Page Title="" Language="C#" MasterPageFile="~/Base/View/Dialog.master" AutoEventWireup="true" CodeFile="MedDlg2.aspx.cs" Inherits="AMR.Main.Med.MedDlg2" %>

    TagPrefix="asp" %>

"Content5" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    "ScriptManager1" runat="server">

I'm new to Silverlight and I appreciate your help.
