Delete Content Source 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 ContentSource?

In simple terms "It enables how the content should be crawled using search service. It might be based upon many options such as URL defined to crawl, type of crawl opted, how and when to crawl".

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

Step 2: Open up Visual Studio 2012 and try to select SharePoint visualwebpart project

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="DeleteContentSourceApp.VisualWebPart1.VisualWebPart1" %>

<div>

<tr>

<asp:label id="Label1" runat="server" text="Delete Content Source - 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 Content Source Name:"></asp:label>

</td>

<td>

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

</td>

</tr>

<tr>

<asp:button id="Button1" runat="server" text="Delete Content Source" forecolor="Orange"

font-bold="true" backcolor="Black" onclick="Button1_Click" width="261px" />

</td>

</tr>

<tr>

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

</td>

</tr>

</table>

</div>

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

using Microsoft.Office.Server.Search.Administration;

using Microsoft.SharePoint;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace DeleteContentSourceApp.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

{

SPSite site = new SPSite("http://win-5c3g1lanj3k:49003/");

SearchContext objSearch = SearchContext.GetContext(site);

Content content = new Content(objSearch);

ContentSourceCollection collection = content.ContentSources;

if (collection.Exists(TextBox1.Text))

{

ContentSource contentSource = collection[TextBox1.Text];

contentSource.Delete();

Label4.Text = TextBox1.Text + " - Content Source Delete Successfully";

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

TextBox1.Text = string.Empty;

}

else

{

Label4.Text = "Content Source Does Not Exsist";

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

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: The content source showing before deleting output of the application looks like this:

Step 9: Data entering output of the application looks like this:

Step 10: Content source deleted output of the application looks like this:
