Introduction:

Recently, we have been working on a sharepoint console app that finds invalid metadata terms assigned to web part properties. To get started we were trying to get all web parts on a publishing page.

Problem​:

There were several CQWP on page which were showing as error webparts when you get them using LimitedWebPartManager.

Solution:

Since CQWP and other publishing site web parts uses HttpContext.Current, we have to create a fake object in order to get it working properly. Here is the code that was included before GetLimitedWebPart call:

   1:  if (HttpContext.Current == null)

   2:  {

   3:  HttpRequest request = new HttpRequest("", web.Url, "");

   4:  HttpContext.Current = new HttpContext(request,

   5:  new HttpResponse(new StringWriter()));

   6:  HttpContext.Current.Items["HttpHandlerSPWeb"] = web;

   7:  WindowsPrincipal wP = new WindowsPrincipal(System.Security.Principal.WindowsIdentity.GetCurrent());

   8:  HttpContext.Current.User = Thread.CurrentPrincipal = wP;

   9:  }​
