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 to create group using 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 Forms Application", as in:

asp.net-web-application.jpg

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="CreateGroupusingCOMApp._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<div>

<table>

<tr>

<asp:Label ID="Label1" runat="server" Text="Create Group in SharePoint 2010 using VS 2010 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>

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

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

</td>

</tr>

<tr>

<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 CreateGroupusingCOMApp

{

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/");

GroupCreationInformation objGroupInfo = new GroupCreationInformation();

objGroupInfo.Title = TextBox1.Text;

objContext.Web.SiteGroups.Add(objGroupInfo);

objContext.ExecuteQuery();

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

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

TextBox1.Text = string.Empty;

}
