Hi, all.
I ran into problems right after upgrade.
Configuration error has occured (see sf_error1.png attachment).
I've foudnd all "4.0.1098.0" version occurences for "Telerik.Sitefinity.Utilities" library references in web.config and replaced to "4.1.1339.0" ("Telerik.Sitefinity.Utilities.dll" library version is "4.1.1339.0" at this moment).
"Could not load file or assembly" exception has occured (see sf_error2.png attachment).
Than I've built my project once again and restarted w3wp application.
So, new exception has occured (see sf_error3.png attachment).
And I don't know what to do... Help me, please.

In addition, last exception always occuring when I see the page in public mode ( localhost/membership-renewals )
But there is no exceptions in edit mode and in preview mode ( localhost/.../Preview ).
So, I feel free to create new pages... but I can't show them to others.

So, there is another problem. I cannot create a page if HTML title contains comma or ampersand etc...
See attachment.
How can I allow to use punctuation marks in title?

Hello Anatoliy,

The first errors say that there is some problem loading dlls - the solution does not have proper reference to the correct dlls or they are not in your bin folder. In the another screenshot I see that there is reference to 1098 which is the official release, so make sure that you set the proper reference and if you have custom controls they do not refer the old dlls

You can alter the page filed validation from Administration >> Settings >>ContentView >> Controls >>
BackendPages >> Views >> BackendPagesCreate >> Toolbar >> Sections

Hello Ivan,

Thanks, I've found and updated needed options in Settings and title problem is resolved.

But I still have a problem with exception ( sf-error3.png )
1) I've checked all Telerik.Sitefinity.* dll's from bin folder. All these dll's versions are 4.1.1339.0.
2) I've checked all solutions for 4.0.1098.0. Found some occurences in ToolboxesConfig.config file and replaced to 4.1.1339.0.
3) I've checked all database objects for 4.0.1098.0. Found some occurences in sf_data_objects table and replacet to 4.1.1339.0.

Exception ( sf-error3.png ) is still being thrown but I've got to isolate the sore! So, If one of my custom layouts is used on the page - the exception will be thrown invariably!
I cannot understand how my custom layouts are take effect. Please, help me!

Here is some information.

1)Custom layout source code:

namespace SitefinityWebApp.Layouts.PageLayouts.TwoColumns
    public class LayoutControl : CustomLayoutControl
        protected override string LayoutTemplate
                return "SitefinityWebApp.Layouts.PageLayouts.TwoColumns.Layout.LayoutTemplate.ascx";

using Telerik.Sitefinity.Web.UI;
namespace SitefinityWebApp.Layouts
    public abstract class CustomLayoutControl : LayoutControl
        protected abstract string LayoutTemplate get;
        public override sealed string Layout
                return LayoutTemplate;
        public override sealed string AssemblyInfo
                return GetType().ToString();
                base.AssemblyInfo = value;

2) ASCX Layout template:

<%@ Control Language="C#" %>
<div runat="server" class="sf_cols bodyInner">
    <div runat="server" class="sf_colsOut bodyColumn bodyLeftColumn bodyContent">
        <div runat="server" class="sf_colsIn bodyColumnInner"></div>
    <div runat="server" class="sf_colsOut bodyColumn bodyRightColumn black-green">
        <div runat="server" class="sf_colsIn bodyColumnInner"></div>

3) Occurences in .csproj file:

<Compile Include="Layouts\PageLayouts\TwoColumns\LayoutControl.cs" />
<EmbeddedResource Include="Layouts\PageLayouts\TwoColumns\Layout\LayoutTemplate.ascx" />

4) Layout usage from sf_object_data table:

Columns: 'app_name', 'collection_index', 'dictionary_key', 'id', 'last_modified', 'object_type', 'parent_prop_id', 'voa_class', 'voa_version', '<_editable>k___backing_field', 'allow_security', 'can_inherit_permissions', 'culture', 'id2', 'inherits_permissions', 'is_data_source', 'is_layout_control', 'ownr', 'place_holder', 'shred', 'sibling_id', 'content_id', 'published', 'id3', 'published2', 'page_id', 'description_', 'caption_', 'original_control_id'
Values: 'WildApricot/', '0', 'NULL', 'B132A9D8-A4A1-42E5-B7DC-CCBBA68F14DD', '2011-04-27 13:23:43.680', 'SitefinityWebApp.Layouts.PageLayouts.TwoColumns.LayoutControl', 'NULL', '811529188', '2', 'NULL', '0', '0', 'NULL', 'NULL', '0', '0', '1', 'C35AFCAD-8449-4E13-A6EF-62DDB0059C81', 'MainPlaceHolder', '1', 'F7F76018-472C-44B4-8988-0881273FE2D1', 'NULL', 'NULL', 'NULL', 'NULL', 'NULL', 'NULL', 'TwoColumns', '71270A7B-584F-4446-A1A5-7082D07C84A6'

6) There are no exceptions in Edit and Preview mode (even If i use any custom layouts in page).

7) There are no logs in App_Data\Sitefinity\Logs\ folder (I've deleted old ones yesterday and ran into exception today many times - and there are no new logs yet).

Thanks a lot for any assistance!

I'm seriously worried about state of affairs.
It's impossible to use Sitefinity because now there is no one usable page which contain at least one custom layout.
And it's impossible to create new custom layouts after 4.0 -> 4.1 upgrade because all of them cannot dropped on page in edit Mode - see sf_error4.png attachment.
And I really don't have the opportunity to revert 4.0 version: there were a serious bug with dropped SQL connection which was fixed in 4.1 ( ). This bug is endurable for my local server but absolutely inadmissible for live publication.

Has there been any progress on this issue? The Telerik support teams seems to have grown quiet. I am having the same issue, I put in a ticket to the support team a few days ago:

And I have not had a response in over 24 hours since my last post. Is this a bug? It would be nice to know that using custom Layout Controls is a bug in 4.1. This is frustrating and infuriating. No one seems to know anything about how to solve this. My custom Layout Control was working in 4.0 before the upgrade and now it isn't. I can only see it in Edit mode and Preview mode, but on the live page I keep getting an "Invalid Layout Template" exception. What is going on?

Any response at this point from the Telerik team would be greatly appreciated. Leaving us in the dark is not good practice!

Hi Leng,

Please take a look at this forum post where I attached a working sample and video that shows how the control works properly without throwing an exception.

I hope this helps.

All the best,
