Delete Taxonomy Group 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 Taxonomy?

In simple terms "Taxonomy is formally defined as the practice of classification according to natural relationships which can be tagged or filtered whereby associating with the specific term store".

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 Visual Web Part" project, as in:

Step 3: Select "Deploy as a farm solution" as in the following and click the "Finish" button. Now an empty project will be created.

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="TaxonomyGPDelete.VisualWebPart1.VisualWebPart1" %> <div align="center"> <table style="font-family: Verdana"> <tr> <td colspan="2"> <asp:label id="Label1" runat="server" text="Delete Taxonomy Group - 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" width="117px"></asp:textbox> </td> </tr> <tr> <td colspan="2" style="text-align: center"> <asp:button id="Button1" runat="server" text="Delete Group" forecolor="Orange" font-bold="true" backcolor="Black" onclick="Button1_Click" width="142px" style="margin-left: 0px" /> </td> </tr> <tr> <td colspan="2" style="text-align: center"> <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.SharePoint;
using Microsoft.SharePoint.Taxonomy;
using System;
using System.ComponentModel;
using System.Web.UI.WebControls.WebParts;namespace TaxonomyGPDelete.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:46908/");
TaxonomySession session = new TaxonomySession(site);
TermStore termStore = session.TermStores["Managed Metadata Service"];
Group group = termStore.Groups[TextBox1.Text];
group.Delete();
termStore.CommitAll();
Label4.Text = TextBox1.Text + " - Taxonomy Group Deleted Successfully";
Label4.ForeColor = System.Drawing.Color.Green;
TextBox1.Text = string.Empty;
}
}
}
}

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

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

Step 8: The taxonomy group available output of the application looks like this:

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

Step 10: Taxonomy group deleted output of the application looks like this:
