Scriptmanager and RadMenu

[Philip Saltskog]

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

Hi Philip Saltskog,

This error may occur if you are mixing different versions of ASP.NET Ajax and RadControls for ASP.NET Ajax e.g. ASP.NET Ajax 1.0 and RadControls for ASP.NET Ajax built for .net 3.5. Please make sure you are using the right version of the Telerik.Web.UI assembly - the version number should end with 35 (2008.3.1314.35) if you are targeting .net 3.5 and with 20 (2008.3.1314.20) when targeting .net 2.0 and ASP.NET Ajax 1.0.

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"/>

to

<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

Hello Philip Saltskog,

I cannot tell where the problem is based on your explanation. Could you please open a support ticket and send us a sample project which demonstrates the issue? It would help us troubleshoot the problem and provide a solution. Thanks.

Sure, but before i will try to eliminate some .dll wich is not used here and other stuff so I have a pretty clean copy of it.
