Create Document Set In SharePoint 2013 Document Library Using CSOM

In this blog, you will learn how to create Document Set in SharePoint 2013 Document Library, using CSOM.

Introduction

In this blog, I would like to explain how to create Document Set in Document Library, using CSOM. A Document Set is a group of related documents, which can be created in one step and then managed as a single entity.

Activate Document Set Feature

We need to activate it before you can create or configure new Document Set content types.

• Go to the top-level site in the site collection for which you want to enable Document Sets.
  
• Site Actions menu--> click Site Settings.
  
• Site Collection Administration - Site collection features.
• Find Document Sets in the list and then click Activate.

Add Document Set as a Content Type to your Document Library

• Go to Document Settings and change the Advanced Settings to Allow management of content types.
  
  
  
  
• Go to the Settings- add from existing site content types and find the Document Set content type. Select Document Set and click Add.
  
  
  
• Go to your Document library and select New Document -> Document Set from the drop-down list.
  
  
  

Here, we will see how to create a Document Set programmatically, using csom.

Source Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.DocumentSet;
namespace DocumentSet
{
    class Program {
        static void Main(string[] args) {
            string siteURL = "https://gowtham.sharepoint.com";
            ClientContext clientContext = new ClientContext(siteURL);
            List list = clientContext.Web.Lists.GetByTitle("TestLibrary1");
            clientContext(list.RootFolder);
            clientContext.ExecuteQuery();
            var itemInfo = new ListItemCreationInformation();
            itemInfo.UnderlyingObjectType = FileSystemObjectType.Folder;
            itemInfo.LeafName = docSetName;
            itemInfo.FolderUrl = list.RootFolder.ServerRelativeUrl;
            var item = list.AddItem(itemInfo);
            item["ContentTypeId"] = "0x0120D520";
            item["HTML_x0020_File_x0020_Type"] = "SharePoint.DocumentSet";
            item.Update();
            clientContext.ExecuteQuery();
        }
    }
}

Copy the code, shown above, paste it in Visual Studio and run. Document Set created successfully.
