Hi,

I am developing some modules with ClientAPI and encountered that when I have 2 modules with ControlMethod callbacks on a single page it doesn't work. There is no problem with the modules when used individually, anyone have any idea? the below are my code snippts:

///////////////// Module 1 - ViewMapClient.ascx.cs /////////////////////

    [ControlMethodClass("MapLingo.MapClient")]
    partial class ViewMapClient : PortalModuleBase, IActionable
    {

       protected void Page_Init(object sender, System.EventArgs e)
        {
            ClientAPI.HandleClientAPICallbackEvent(this.Page);
            ClientAPI.RegisterControlMethods(this, this.ID);
        }

        [ControlMethod()]
        public string Validate(string address)
        {

             //do some stuff

             return "somestring";

        }
    }

///////////////// Module 1 - ViewMapClient.ascx/////////////////////

<%@ Control Language="C#" Inherits="MapLingo.MapClient.ViewMapClient"
    AutoEventWireup="true" CodeBehind="ViewMapClient.ascx.cs" %>
   
<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"
    TagPrefix="asp" %>   

     <script type="text/javascript">
         function validate() {
             dnn.xmlhttp.callControlMethod('MapLingo.MapClient.ViewMapClient', 'Validate', { address: 'Somestring' }, validateResultSuccess, validateResultFail);
        }

        function validateResultFail(payload, ctx, req) {
            error: ' + payload);
        }

        function validateResultSuccess(payload, ctx, req) {
            oken: ' + payload);
        }
    </script>

<a href="#" onclick="validate()">test</a>

///////////////// Module 2 - ViewMapSearch.ascx.cs /////////////////////

    [ControlMethodClass("MapLingo.MapMapSearchResult")]
    partial class MapMapSearchResult: PortalModuleBase, IActionable
    {

       protected void Page_Init(object sender, System.EventArgs e)
        {
            ClientAPI.HandleClientAPICallbackEvent(this.Page);
            ClientAPI.RegisterControlMethods(this, this.ID);
        }

       protected void Page_Load(object sender, System.EventArgs e)
        {
            ClientScriptManager script = Page.ClientScript;
            StringBuilder scriptToInject = new StringBuilder();
            scriptToInject.AppendLine("<script type=\"text/javascript\">");
            scriptToInject.AppendLine("function mapSearchResultSuccess(payload, ctx, req) {");
            scriptToInject.AppendLine("var ctx = { ns: '"+this.ClientID+"_' };");
            scriptToInject.AppendLine("$get(ctx.ns + 'divResults').innerHTML = payload;}");
            scriptToInject.AppendLine("</script>");
            script.RegisterStartupScript(this.GetType(), "CallingScript", scriptToInject.ToString());
        }

        [ControlMethod()]
        public string Search(string address)
        {

             //do some stuff

             return "somestring";

        }
    }

///////////////// Module 2 - ViewMapSearch.ascx /////////////////////

<%@ Control Language="C#" Inherits="Maplingo.MapSearchResult.ViewMapSearchResult"
    AutoEventWireup="true" CodeBehind="ViewMapSearchResult.ascx.cs" %>

<script type="text/javascript">
    function mapSearchResultFail(payload, ctx, req) {
        error: ' + payload);
    }

    function mapSearchResultUpdate()
    {
        dnn.xmlhttp.callControlMethod('MapLingo.MapSearchResult.ViewMapSearchResult', 'Search', { address: 'SomeString' }, mapSearchResultSuccess, mapSearchResultFail);
    }
</script>
<div id="divResults" runat="server">
</div>

Thanks for taking the time to reply. I am reffering to 2 different modules on a same page (i have posted the code snippets in my previous post). I have seen your templates and much of the codes I created are referenced from your templates.
