1 – I already tried that and in debug mode I see it adding the additional content type, but then nothing happens in the sharepoint UI. Very strange…

2 – Also I’ve been experimenting with this and also the instruction DocumentSet.Create that has a properties hashtable parameter does not seem to work, I don’t see in sharepoint UI the properties.

3 – Do you have code to insert a document inside a document set, I’ve seen a couple in the internet, but nothing works

By the way here’s the code:

SPSite site = new SPSite(“http://win-n2bu1ltoqd9/sites/extranet”);
SPWeb web = site.OpenWeb();

web.AllowUnsafeUpdates = true;
//TODO: Get Site Content Types
//Associar Esses CTs ao Document Set
string s = String.Empty;
SPContentType ct = web.ContentTypes["TemplateAlfa"];
SPContentType ctDocSet = web.ContentTypes["Document Set"];

SPFolder folder = web.GetFolder(“ListaProcessos/Processos”);

Microsoft.Office.DocumentManagement.DocumentSets.DocumentSet docSet =
Microsoft.Office.DocumentManagement.DocumentSets.DocumentSet.GetDocumentSet(folder);

//add the default document to your document set template
//SPContentType customDocType = web.ContentTypes["Document Set"];

////get a an instance of DocumentSetTemplate for the new document set
DocumentSetTemplate newDocumentSetTemplate =
DocumentSetTemplate.GetDocumentSetTemplate(ctDocSet);

////newDocumentSetTemplate.DefaultDocuments.Add(“texte.txt”, customDocType.Id, documentoBytes);

////.Folder.Files.Add(“texte.txt”, documentoBytes);

////Add the new content type, make the field shared, and add it to the welcomepage

newDocumentSetTemplate.AllowedContentTypes.Add(ct.Id);

newDocumentSetTemplate.Update(true);
ct.Update();

web.Update();

web.Dispose();

I haven’t tried this out but the DocumentSetTemplate has a property AllowedContentTypes. I assume you can use the Add method on that to add a child content type to the documentset through code.

Also do you know a way to add child content types to a document set using c# OM?
