JavaScriptSerializer seems to ignore the maxJsonLength configuration

Question

I was facing the max json length problem so as suggested by various sources on the internet, i increased the default json length in the configuration file like

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="900000000"></jsonSerialization>
      </webServices>
    </scripting>
  </system.web.extensions>

but the problem persisted. Then i came across a fantastic blog post that suggested to write my own ActionResult. i am using the telerik grid for mvc along with mvc3.net. Any idea why the serializer ignoring the config.
