DeleteGroup in SharePoint 2010 Programmatically Using VS 2010 Via COM

Introduction

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" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

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

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <center>

        <div>

            <table>

                <tr>

                    <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>

                    </td>

                </tr>

                <tr>

                    <td>

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

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

                    </td>

                    <td>

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

                    </td>

                </tr>

                <tr>

                    <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>

                </tr>

                <tr>

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

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

                    </td>

                </tr>

            </table>

        </div>

    </center>

    </form>

</body>

</html>

 

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)

        {

            TextBox1.Focus();

        }

        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;

            }

            else

            {

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

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

                objContext.Web.SiteGroups.Remove(objGroup);

                objContext.ExecuteQuery();

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

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

                TextBox1.Text = string.Empty;

            }

        }

    }

}

 

Step 4: The output of the application looks like this:

 

delete-group-in-sharepoint2010.jpg

Step 5: Group exists output of the application looks like this:

 

Group-exists-output -sharepoint2010.jpg
 

Step 6: Data entering output of the application looks like this:

 
 vs2012-delete-group-in-sharepoint2010.jpg

 

Step 7: The output of the group deleted SharePoint application looks like this:
