Here is Part 1

In this article we will be seeing how to add or remove the heading and links from the Quick Launch Navigation in SharePoint 2010.

SPNavigationNodeCollection nodeColl = web.Navigation.QuickLaunch;
SPNavigationNode heading1 = new SPNavigationNode("My Articles","");
nodeColl.AddAsFirst(heading1);
SPNavigationNode heading2 = new SPNavigationNode("My Blogs", "");
nodeColl.AddAsLast(heading2);

SPNavigationNodeCollection nodeColl = web.Navigation.QuickLaunch;
                    foreach (SPNavigationNode heading in nodeColl)
                    {
                        if (heading.Title == "My Articles")
                        {
                            SPNavigationNode link1 = new SPNavigationNode("Articles", "http://www.csharpcorner.com/", true);
                            heading.Children.AddAsFirst(link1);
                        }
                        if (heading.Title == "My Blogs")
                        {
                            SPList list = web.Lists.TryGetList("Blogs");
                            SPNavigationNode link2 = web.Navigation.GetNodeByUrl(list.DefaultViewUrl);
                            if (link2 != null)
                            {
                                link2 = new SPNavigationNode(list.Title, list.DefaultViewUrl);
                                heading.Children.AddAsFirst(link2);
                            }
                        }
                    }
