[Solved] Telerik.Charting and prometheus ajaxmanager

[NS]

Hello,
I developed a page with two prometheus charts and a prometheus ajaxmanager on a page.

This page works perfectly on my development machine. However, when I deploy it to production I get the following error:

Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.MissingMethodException: Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'.


Stack Trace:


[MissingMethodException: Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'.]
   Telerik.Web.UI.RadAjaxControl.PerformRender() +0

If I remove on my form the following lines the problem goes away:

strange that this works in development but not in production ...
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <AjaxSettings>
                    <telerik:AjaxSetting AjaxControlID="dliChartType">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="RadChart1" LoadingPanelID="LoadingPanel1" />
                            <telerik:AjaxUpdatedControl ControlID="RadChart2" LoadingPanelID="LoadingPanel1" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                    <telerik:AjaxSetting AjaxControlID="dliChartColor">

                            <telerik:AjaxUpdatedControl ControlID="RadChart2" LoadingPanelID="LoadingPanel1" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                </AjaxSettings>
            </telerik:RadAjaxManager>

Hi Nicolas ,

I have seen such error once with an old version of ASP.NET AJAX - please verify that you are using latest version of ASP.NET AJAX.

All the best,

Hello Vlad,
I did an install of the latest version of the ajax framework and that did the trick ! Thank you.

It was however the same version: 1.0.61025, but there was a difference in size of some of the javascript files in the ms ajax folder.

Regards,
Nicolas
