Reset to Site Definition 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 reset to site definition?

In simple terms "It enables removal of all the customizations from a page or site".

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

Step 2: Open up Visual Studio 2012 and try to create a "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="ResetSiteDefApp.VisualWebPart1.VisualWebPart1" %>

<table>

<tr>

<asp:label id="Label1" runat="server" text="Reset Site Defination in SharePoint 2010 using VS 2012"

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

</td>

</tr>

<tr>

<asp:button id="Button1" runat="server" text="Reset Site Defination" font-names="Verdana"

width="203px" backcolor="Orange" font-bold="True" onclick="Button1_Click" />

</td>

</tr>

</table>

</div>

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 ResetSiteDefApp.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)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

SPSite site = new SPSite("http://win-5c3g1lanj3k:29782/");

foreach (SPWeb web in site.AllWebs)

{

web.RevertAllDocumentContentStreams();

}

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: The reset to site definition output application looks like this:
