Hello steve marson,

How are you referencing the Prometheus controls? Are they in the bin folder of your website (are you using a website or a webapplication for that matter) or you have them in GAC and reference them in the web.config file?

Usually such errors occur when you have referenced different versions of the same assembly (one from GAC one from bin)  or different assemblies with the same classes.

All the best,

Hi steve marson,

We just tested the Prometheus RadAjax control under OrcasBeta1 virtual machine and it seems to be running just fine. Have you tried the same application on a different computer?

Hello steve marson,

This looks like it might be a bug in RadControls "Prometheus".  We are currently investigating the issue and will get back to you if you when we have more information.

Hello steve marson,

The file you provided is indeed a website project, however, it does not have any RadAjaxManager controls in it. Are you sure you attached the correct file?

Hello Steve,

Excluding the errors thrown by the web.config, once we have replaced it with a default "AjaxEnabled" config file, there were no errors. On the page you provided we found only a ScriptManager and RadAjaxManager with nothing else and no updated controls. Are you getting the error only by placing an empty AjaxManager with no AjaxSettings and updated controls?

All the best,
Steve

just take script manager and put it before your code like in this example:
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
        <telerik:radupload runat="server"></telerik:radupload>
        <telerik:RadTextBox ID="RadTextBox1" Runat="server">

Hi Telerik Team,

Here is my problem/question regarding the scriptmanager error:  After I removed this tag from the Master  control file ( <asp:ScriptManager ID="ScriptManager1" runat="server" EnableScriptLocalization="true" EnableScriptGlobalization="true">
                  </asp:ScriptManager> , it still works in Dev and QA environment without errors.  Then, when we deployed the application/code to production, it threw an error "The control with ID 'FromDate' requires a ScriptManager on the page " in the exception. That's very strange.  I think we have the same version of dll in the GAC, but I will need the production support team to confirm that's the case.

Any idea why I got that error in Production, but not in QA and Dev??? many thanks. JC

Hello Srivalli,

Please make sure that you have script manager defined on the page:
http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/general-troubleshooting#error-message-the-control-with-id-controlid-requires-a-scriptmanager-on-the-page-the-scriptmanager-must-appear-before-any-controls-that-need-it

Also, make sure that you are not using the ToolkitScriptManager since Telerik controls are currently not compatible with Ajax Control Toolkit:
http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/general-troubleshooting#telerik-controls-are-incompatible-with-ajax-control-toolkit
