DeleteGroup in SharePoint 2010 Programmatically Using VS 2010 Via COM


Today, in this article let's play around with one of the interesting and most useful concepts in SharePoint 2010.

Question: What is group via COM?

In simple terms "To enables a group to be deleted using the client object model which serves in managing users, permission levels and so on".


Step 1: Open Visual Studio 2010 and create an "ASP.NET Web Application", as in:

Now two references need to be added to the application, they are:

  • Microsoft.SharePoint.Client

  • Microsoft.SharePoint.Client.Runtime


Step 2: The complete code of webform1.aspx looks like this:


<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="DeleteGroupCOMApp._Default" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">

<head id="Head1" runat="server">




    <form id="form1" runat="server">





                    <td colspan="2">

                        <asp:Label ID="Label1" runat="server" Text="Delete Group in SharePoint 2010 using VS 2012 via COM"

                            Font-Bold="true" Font-Size="Large" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>





                        <asp:Label ID="Label2" runat="server" Text="Please Enter Group Name" Font-Size="Large"

                            Font-Names="Verdana" Font-Italic="true"></asp:Label>



                        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>




                    <td colspan="2" align="center">

                        <asp:Button ID="Button1" runat="server" Text="Delete Group - COM" Font-Names="Verdana"

                            Width="213px" BackColor="Orange" Font-Bold="True" OnClick="Button1_Click" />




                    <td colspan="2" align="center">

                        <asp:Label ID="Label5" runat="server" Font-Bold="true" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>










Step 3: The complete code of webform1.aspx.cs looks like this:


using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Microsoft.SharePoint.Client;

namespace DeleteGroupCOMApp


    public partial class _Default : System.Web.UI.Page


        protected void Page_Load(object sender, EventArgs e)




        protected void Button1_Click(object sender, EventArgs e)


            if (string.IsNullOrEmpty(TextBox1.Text))


                Label5.Text = "Please Enter Some Values";

                Label5.ForeColor = System.Drawing.Color.Red;




                ClientContext objContext = new ClientContext("http://win-kv3bo1rqqf7:25339/");

                Group objGroup = objContext.Web.SiteGroups[int.Parse(TextBox1.Text)];



                Label5.Text = TextBox1.Text + "Group Deleted Successfully ";

                Label5.ForeColor = System.Drawing.Color.Green;

                TextBox1.Text = string.Empty;
