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:
![open-asp.net-web-application.jpg]()
Now two references need to be added to the application, they are:
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:
![output-of-the-group-deleted-sharepoint-application.jpg]()
