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:

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

using Microsoft.SharePoint;

using Microsoft.SharePoint.Navigation;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace SubNodeApp.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) || string.IsNullOrEmpty(TextBox4.Text) ||string.IsNullOrEmpty(TextBox5.Text) || string.IsNullOrEmpty(TextBox6.Text))

{

Label5.Text = "Please Enter Some Values";

Label5.ForeColor = System.Drawing.Color.Red;

}

else

{

try

{

SPSite site = new SPSite("http://win-5c3g1lanj3k:46908/");

SPWeb web = SPContext.Current.Web;SPNavigationNodeCollection navigationNode = web.Navigation.TopNavigationBar;

SPNavigationNode mainHeading = new SPNavigationNode(TextBox1.Text, TextBox2.Text, true);

navigationNode.AddAsLast(mainHeading);
