RadStyleSheetManagerError.png

Hi!

We are going to use RadStyleSheetManager to merge and comress all stylesheets.
But when activating external stylesheets we get a serialization error. If we don't use external stylesheets it works fine.
We are using SqlServer as StateServer.
Telerik version: 2012.2.918.35
See attached file for error.

Any ideas on what could be wrong?

Below are codesnippets from web.config and the aspx-page.

Web.Config

<appSettings>

<add key="Telerik.Web.UI.StyleSheetFolders" value="/Style" />

</appSettings>

<system.web>

<httpHandlers>

<add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2012.2.918.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

</httpHandlers>

</system.web>

aspx-page

<telerik:RadStyleSheetManager runat="server" ID="rssm">

<StyleSheets>

<telerik:StyleSheetReference Path="core.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

Hello Andreas,

Interesting, it seems that for some reason ASP.NET is trying to serialize our InsecureExternalStyleSheetException class which is an exception class, which RadStyleSheetManager uses when validating external style sheets. We will need to troubleshoot that one a bit more before stating what might be going wrong. I will write a follow up in this thread after we conduct some tests with a StateServer.
