Question

I am trying to use C# code in an aspx page within SharePoint 2010. I keep getting the “Code blocks are not allowed” error.

My aspx page located at (server)/SitePages/ajax.aspx: (edited in SharePoint Designer 2010 if it matters)

<%@ Page Language="C#" %>
<script runat="server">
    Response.Write("Hello world");
</script>

I added the following to web.config at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG

<PageParserPath VirtualPath="/SitePages/ajax.aspx" CompilationMode="Always" AllowServerSideScript="true" />

Here is the same line that I added to web.config, shown in context:

<SharePoint>
  <SafeMode 
        MaxControls = "200"  
        CallStack = "false"
        DirectFileDependencies ="10"
        TotalFileDependencies = "50"
        AllowPageLevelTrace = "false"
        >
        <PageParserPaths>
            <PageParserPath VirtualPath="/SitePages/ajax.aspx" CompilationMode="Always" AllowServerSideScript="true" />
        </PageParserPaths>

Why do I still get the “Code blocks” error? Is there another security switch somewhere?

(I know custom web parts are the preferred solution, but I don’t think that will suffice here because the return value should be json – this is a page to hit via ajax to get data.)

I suppose, you have to define PageParserPath element in an Web application web.config that is located C:\inetpub\wwwroot\wss\VirtualDirectories[application folder]\web.config.
