Hi there!

I'm adding ScriptManager as dynamical like this.

    
                Protected Overloads Overrides Sub OnPreInit(ByVal e As EventArgs)  
        
                    Dim myScriptManager As ScriptManager = ScriptManager.GetCurrent(Me)  
        
                    If myScriptManager Is Nothing Then 
        
                        myScriptManager = New ScriptManager()  
        
                        myScriptManager.ID = "ScriptManager1" 
        
                        Dim myControl As Control = Me.FindControl("Form1")  
        
                        If myControl IsNot Nothing Then 
        
                            myControl.Controls.AddAt(0, myScriptManager)  
        
                        End If 
        
                    End If 
        
                    MyBase.OnPreInit(e)  
        
                End Sub

And I get this error

    
            System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.InvalidOperationException: The control with ID 'R1t' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

               at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I'm also using a handler to get cache and nicer url without querys. It's more code behind here...

    
                Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest  
        
                    Dim url, pathTranslated, strPath As String 
        
                    url = context.Items("url")  
        
                    pathTranslated = context.Items("path")  
        
                    strPath = HandleRequest(context, url, pathTranslated)  
        
                    context.Handler = PageParser.GetCompiledPageInstance(url, strPath, context)  
        
                    context.Handler.ProcessRequest(context)  
        
                End Sub

In the web.config it looks like this

    
                    <httpHandlers> 
        
                        <remove verb="*" path="*.asmx"/>  
        
                        <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>  
        
                        <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>  
        
                        <add verb="GET,HEAD" path="ScriptResource.axd" validate="false" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>  
        
                  <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" /> 
        
                  <add verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI"/>  
        
                  <add verb="*" path="tbimage.aspx" type="RenderUtils.HttpImageHandler, RenderUtils"/>  
        
                  <add verb="*" path="*.aspx" type="clsHttpHandler.HttpXmlHandler, clsHttpHandler"/>  
        
                </httpHandlers>

Do I need to use RadScriptManager? Something gets wrong when I add the context back. Any ideas here?

/Thanks

It is the latest version of asp.net ajax, but I've a old RadMenu.dll in the bin lib and I've deleted now.
I don't think this is a Telerik issue coz the scriptmanager will not registred so I change

    
            <xhtmlConformance mode="Legacy"/>

    
            <xhtmlConformance mode="Transitional"/>

and now the scriptmanager will registred on the page, but the Ajax RadMenu cant still find it!??

The Radmenu is placed in a usercontroller as will load from default.aspx inherit from basepage. In another usercontrol I've a RadTreeView and it will loaded similar.
The RadMenu get me same error, but the RadTreeView will work?

I've read about scriptmanager and som registry problem, but now can I really see the manager on each page and the menu should could pick it up?

/Thanks
