Create Term 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 Term?

In simple terms "It allows you to define terms in a hierarchical collection centrally, and create a managed metadata field; that is, reference term sets".

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 on 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="CreateTermApp.VisualWebPart1.VisualWebPart1" %>

<div>

<tr>

<asp:label id="Label1" runat="server" text="Create Term - 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>

<td>

<asp:label id="Label3" runat="server" text="Please Enter TermSet Name:"></asp:label>

</td>

<td>

<asp:textbox id="TextBox2" runat="server"></asp:textbox>

</td>

</tr>

<tr>

<td>

<asp:label id="Label5" runat="server" text="Please Enter Term Name:"></asp:label>

</td>

<td>

<asp:textbox id="TextBox3" runat="server"></asp:textbox>

</td>

</tr>

<tr>

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

backcolor="Black" onclick="Button1_Click" width="167px" />

</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 Microsoft.SharePoint.Taxonomy;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace CreateTermApp.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) || string.IsNullOrEmpty(TextBox2.Text)||string.IsNullOrEmpty(TextBox3.Text))

{

Label4.Text = "Please Enter Some Values";

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

}

else{SPSite site = new SPSite("http://win-5c3g1lanj3k:16101/");

TaxonomySession session = new TaxonomySession(site);

TermStore termStore = session.TermStores["Managed Metadata Service"];

Group group = termStore.CreateGroup(TextBox1.Text);

TermSet termSet = group.CreateTermSet(TextBox2.Text);

Term term = termSet.CreateTerm(TextBox3.Text, 1033);

termStore.CommitAll();

Label4.Text = TextBox3.Text + " - Taxonomy Term Created Successfully";

Label4.ForeColor = System.Drawing.Color.Green;TextBox1.Text = string.Empty;

TextBox2.Text = string.Empty;TextBox3.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: Term created output of the application looks like this:
