Assign New Role in SharePoint 2010 Programmatically Using VS 2012

Introduction

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

Question: What is Role?

In simple terms "It is used to provide the permissions of either SPList, SPListItem or SPWeb".

Step 1: Open SharePoint 2010 Central Administration and navigate to a specific site.

Step 2: Open up Visual Studio 2012 and try to "SharePoint Visual Web Part" project, as in:

Step 3: Select "Deploy as a farm solution" as in the following and click the "Finish" button.

Step 4: The complete code of visualwebpart1usercontrol.ascx looks like this:

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>

<%@ Assembly Name="Microsoft.Web.CommandUI, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"

Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Register TagPrefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Register TagPrefix="asp" Namespace="System.Web.UI" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>

<%@ Import Namespace="Microsoft.SharePoint" %>

<%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages"

Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="VisualWebPart1.ascx.cs"

Inherits="RoleAssignmentApp.VisualWebPart1.VisualWebPart1" %>

<div>

<tr>

<asp:label id="Label1" runat="server" text="Assign Role - SharePoint 2010 via Visual Studio 2012"

font-bold="true" forecolor="Maroon" font-size="Large"></asp:label>

</td>

</tr>

<tr>

<td>

<asp:label id="Label2" runat="server" text="Please Enter Group Name:"></asp:label>

</td>

<td>

<asp:textbox id="TextBox1" runat="server"></asp:textbox>

</td>

</tr>

<tr>

<asp:button id="Button1" runat="server" text="Assign Role" forecolor="Orange" font-bold="true"

backcolor="Black" onclick="Button1_Click" width="176px" />

</td>

</tr>

<tr>

<asp:label id="Label4" runat="server" font-bold="true"></asp:label>

</td>

</tr>

</table>

</div>

</center>

Step 5: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:

using Microsoft.SharePoint;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace RoleAssignmentApp.VisualWebPart1

{

[ToolboxItemAttribute(false)]

public partial class VisualWebPart1 : WebPart

{

// Uncomment the following SecurityPermission attribute only when doing Performance Profiling using

// the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready

// for production. Because the SecurityPermission attribute bypasses the security check for callers of

// your constructor, it's not recommended for production purposes.

// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]

public VisualWebPart1()

{

}

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

InitializeControl();

}

protected void Page_Load(object sender, EventArgs e)

{

TextBox1.Focus();

}

protected void Button1_Click(object sender, EventArgs e)

{

if (string.IsNullOrEmpty(TextBox1.Text))

{

Label4.Text = "Please Enter Some Values";

Label4.ForeColor = System.Drawing.Color.Red;

}

else

{

SPWeb web = SPContext.Current.Web;

SPGroup group = web.SiteGroups[TextBox1.Text];

SPRoleDefinition rDefination = web.RoleDefinitions.GetByType(SPRoleType.Administrator);

SPRoleAssignment rAssignment = new SPRoleAssignment(group);

rAssignment.RoleDefinitionBindings.Add(rDefination);

web.RoleAssignments.Add(rAssignment);

web.Update();

Label4.Text = SPRoleType.Administrator.ToString() +" - Role Assigned Successfully for "+TextBox1.Text+ " Group";

Label4.ForeColor = System.Drawing.Color.Green;

TextBox1.Text = string.Empty;

}

Step 6: Deploy the solution file and add the new webpart to a SharePoint site.

Step 7: The output of the application looks like this:

Step 8: Data entering output of the application looks like this:

Step 9: Role created output of the application looks like this:
