Hi friend

i have faced a problem regrading ajax.

i built an appliaction in dnn .net(3.5) witj ajax

in page disgn i have added script manager

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="false">
</asp:ScriptManager>

and in page load event i write following

if (DotNetNuke.Framework.AJAX.IsInstalled())
        {
            DotNetNuke.Framework.AJAX.RegisterScriptManager();
        }

after creating zip, when insatll module, it shows following -

Unhandled error loading module.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unhandled Error Adding Module to ContentPane ---> 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.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 ---

but the problem is that, if i remove script manager from the page design, it again shows that before using update panel i have to use script manager.

pls tell me how can solve this problem
