  I am getting "Cannot write to a closed TextWriter. " when it is inside of a partial view or template. I just upgraded to the latest Telerik package and started getting this on code that was there prior. If I take the same stuff and put it directly in the head of the Master Page, then it works. I like to keep the stylesheet registrar in its own control due to some of the site's complexities.
  
  Thanks,
  Mike

  Hey Telerik, is there anyone out there? It seems like I have posted quite a few times on this site and not one has been answered by you guys. Pretty sad since I am a proponent of your tools and I usually put them in my client's solutions. Would be nice if you guys answered every once in a while. Thanks.

  Hi Mike,

  The forums are a community resource and although we monitor them, we don't guarantee a timely response here. If you need a faster reply, you should use the support ticketing system. It assigns response time (according to the purchased license) to every issue that is submitted and forwards it to the corresponding teams.
  
  As for the problem itself, if you still experience it, please provide a sample project so we can investigate further. We will check it and get back to you right away.

  All the best,

  I have a razor layout file that calls the partial view _MallCommonScripts.cshtml, 
  I setup the ScriptRegistrar as following:
  
  

      var scripts = Html.Telerik().ScriptRegistrar()

          .Globalization(true)

          .jQuery(false).jQueryValidation(false) //disable the jQuery shipped with Telerik, which is of version 1.7.1

          .CombinedComponentFile(true)

          .DefaultGroup(

              g =>

              {

                  g.Add("~/Scripts/jquery-1.8.2.min.js");

                  g.Add("~/Scripts/jquery.validate.min.js");

                  g.Add("~/Scripts/jquery.validate.unobtrusive.min.js");

   

                  g.Combined(true);

                  g.Compress(false);

              });

      scripts.Render(); //will cause "Cannot write to a closed TextWriter" exception

  }

  
  
  And I get the exception "Cannot write to a closed TextWriter".

  The exception is thrown on SOME pages ONLY, which I cannot tell the differences between the pages that throws or not.
  
  The workaround is to change the last line of the ScriptRegistrar setup code from scripts.Render() to "@script":
  
  

  //scripts.Render(); //will cause "Cannot write to a closed TextWriter" exception on SOME pages

  @scripts    //This works for all pages

  
  Wish this helps.
