Step 5

The complete code of visualwebpart1usercontrol.ascx.cs looks like this:

using Microsoft.Office.DocumentManagement.DocumentSets;
using Microsoft.SharePoint;
using System;
using System.Collections;
using System.ComponentModel;
using System.Web.
I.WebControls.WebParts;
namespace DocumentSetApp.VisualWebPart1
{
[ToolboxItemAttribute(false)]
public partial class VisualWebPart1 : WebPart
{
// Uncomment the following SecurityPermission attribute only when doing Performance Profiling using
// the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready
// for production. Because the SecurityPermission attribute bypasses the security check for callers of
// your constructor, it's not recommended for production purposes.
// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]
public VisualWebPart1() { }
protected override void OnInit(EventArgs e)
{
base.OnInit(e); InitializeControl();
}
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Focus();
}
protected void Button1_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
try
{
SPWeb web = SPContext.Current.Web; SPList list = web.Lists[TextBox1.Text];
if (list != null)
{
SPContentType contentType = web.ContentTypes["Document Set"];
if (contentType != null)
{
var hashTable = new Hashtable();
hashTable.Add("DocumentSet", "New Doc Setting"); hashTable.Add("CreatedBy", SPContext.Current.Web.CurrentUser.Name);
hashTable.Add("ModifiedBy", SPContext.Current.Web.CurrentUser.Name);
DocumentSet documentSet = DocumentSet.Create(list.RootFolder, TextBox2.Text, contentType.Id, hashTable,true);
documentSet.Item.ProgId = "SharePoint.DocumentSet"; documentSet.Item.Update();
}
}
}
catch (SPException ex)
{
Label5.Text = ex.Message;
}
Label5.Text = TextBox2.Text + " Document Set Created Successfully";
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
}
}
}
}
