Set Permission to Group 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 setting up permission to a group?

In simple terms "It enables a group to be set up with defined permissions using the client object model".

Step 1: Open Visual Studio 2010 and create an "ASP.NET Web Forms 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="SetPermissionLevelCOMApp._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="Set Permission Level SharePoint 2010 using VS 2012"

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

                    </td>

                </tr>

                <tr>

                    <td>

                        <asp:Label ID="Label3" runat="server" Text="Please Enter Group Name" Font-Size="Large"

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

                    </td>

                    <td>

                        <asp:TextBox ID="TextBox2" runat="server" Width="120px"></asp:TextBox>

                    </td>

                </tr>

                <tr>

                    <td>

                        <asp:Label ID="Label2" runat="server" Text="Please Select Permission Level" Font-Size="Large"

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

                    </td>

                    <td>

                        <asp:DropDownList ID="DropDownList1" runat="server" Width="120px">

                            <asp:ListItem>Full Control</asp:ListItem>

                            <asp:ListItem>Design</asp:ListItem>

                            <asp:ListItem>Contribute</asp:ListItem>

                            <asp:ListItem>Read</asp:ListItem>

                            <asp:ListItem>View Only</asp:ListItem>

                            <asp:ListItem>Records Center Web Service Submitters</asp:ListItem>

                            <asp:ListItem>Approve</asp:ListItem>

                            <asp:ListItem>Manage Hierarchy</asp:ListItem>

                            <asp:ListItem>Restricted Read</asp:ListItem>

                        </asp:DropDownList>

                    </td>

                </tr>

                <tr>

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

                        <asp:Button ID="Button1" runat="server" Text="Show Versions - List" 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 SetPermissionLevelCOMApp

{

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

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            TextBox2.Focus();

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox2.Text))

            {

                Label5.Text = "Please Enter Some Values";

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

            }

            else

            {

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

                GroupCreationInformation objCreateInfo = new GroupCreationInformation();

                objCreateInfo.Title = TextBox2.Text;

                Group objGroup = objContext.Web.SiteGroups.Add(objCreateInfo);

                RoleDefinition objDefination = objContext.Web.RoleDefinitions.GetByName(DropDownList1.SelectedItem.Text);

                RoleDefinitionBindingCollection objBindingColl = new RoleDefinitionBindingCollection(objContext);

                objBindingColl.Add(objDefination);

                objContext.Web.RoleAssignments.Add(objGroup, objBindingColl);

                objContext.ExecuteQuery();

                Label5.Text = "Permission Level Created";

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

                TextBox2.Text = string.Empty;

            }

        }

    }

}
 

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

 

set-permission-level-sharepoint2010.jpg
 

 

Step 5: Data entering output of the application looks like this:

 

vs2012-set-permission-level-sharepoint2010.jpg
 

 

Step 6: Group created with permission output of the application looks like this:

 

Group-created-permission-output.jpg
 

 

Step 7: View permission defined output of the application looks like this:
