Sharepoint 2013 IsContentTypeAllowed always true RRS feed

  • Question

  • Hi, all!

    In Sharepoint 2010 this expression return  only SPList where ContentTypeId is exist. 

    In Sharepoint 2013 it returns always true for any lists.

    var listItems=web.Lists.OfType<SPList>().Where(
                        list =>

    Why is this happening?

  • Hi,

    According to your post, my understanding is that the IsContentTypeAllowed always displayed true.

    I had used the following code snippets to check whether the IsContentTypeAllowed displayed true.

    When I used the “Document” content type, it returned the false.

    using (SPSite site = new SPSite("http://sp"))
                    using (SPWeb web = site.OpenWeb())
                        SPContentType contentType=web.AvailableContentTypes["Document"];
                        if (contentType!=null)
                            SPList list = web.Lists["list1"];
                            list.ContentTypesEnabled = true;
                           // bool flag=IsContentTypeAllowed(list,contentType.Id);
                            if (!list.IsContentTypeAllowed(contentType))
                                Console.WriteLine("The {0} content type is not allowed on the {1} list",
                                contentType.Name, list.Title);                       
                                Console.WriteLine("The contenty type is allowed");
                            Console.WriteLine("The content type not exist..");

    You can also use the below code to check whether your content type ID is equal to the built in content type ID while debugging.
