Hi,

I am trying to run a simple module with ScriptManager and I can run my sample with one control but as soon as I add another instance to the same page I am getting an error message :

Again code is working fine if I have only one instance; but when I add a second I am getting this:

Unhandled error loading module.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error Adding Module to Pane6 ---> System.InvalidOperationException: Only one instance of a ScriptManager can be added to the page. at System.Web.UI.ScriptManager.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.AddedControl(Control control, Int32 index) at System.Web.UI.ControlCollection.Add(Control child) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace ---

my page / code below :

protected

void Button1_Click(object sender, EventArgs e)"New Time : " + System.DateTime.Now.ToString();

<%

{

Label1.Text =

}

I am not using register command/code ; I dropped ScriptManager contol in my control;  that is why I posted complete page source

in any case I was able to fix it; but i am not sure if this 'Kosher' solution

I dropped ScriptManager control on the default.aspx page and I used ScriptManagerProxy control to point to the default page.

is this kosher?????

again I am trying to use ScriptManager control and UpdatePanel control in my module for AJAX postback; if you have a sample that doesn't requer Microsoft AJAX ScriptManager control to refresh/post back UpdatePanel; please post it.

thank you very much; it's working but now I have another problem:

my c# code looks like this, and if you want I can post my html /asp source.

        protected void Timer1_Tick(object sender, EventArgs e)
        {
            RetriveData();
        }

        private void RetriveData()
        {
            WSMonitor.BAL.DataWrapper wrapper = new WSMonitor.BAL.DataWrapper((PortalModuleBase)this);
            string sql = "SELECT top 10 table_name, column_name FROM information_schema.columns order by newid()";
            DataSet data = wrapper.SelectCurrentPortal(sql);
                GridView2.DataSource = data;
                GridView2.DataBind();
        }
        protected void Page_Load(System.Object sender, System.EventArgs e)
        {
            if (DotNetNuke.Framework.AJAX.IsInstalled())
            {
                DotNetNuke.Framework.AJAX.RegisterScriptManager();
               
            }
            if (!Page.IsPostBack)
            {
                RetriveData();
            }
}

if I have only one module on the page, this code is running fine and I am getting data back every 2 seconds, as soon as I add the same module to another pane or another instance to the same pane, the code is stop working for one module but it still works for another; in the nutshell it works only if I have only one module; looks like that script manager can update only one module; is it possible to force the script manager to manage / update multple controls? in my case I need to have 4 modules on the page and every module/control should be able to use ajax to refresh it self with different refresh interval.
