C# TreeView

This article addressing some of the basics of working with a TreeView control; the commodity will abode dynamically abacus TreeNodes to a TreeView control, earching the nodes to find and highlight a single node or a collection of nodes matching a search term against the TreeNode's tag, text, or name properties, and manually or programmatically selecting nodes.

The application solution contains a single Windows Application project comprised;all cipher supplied in abutment of this activity is independent in two anatomy classes; one is the capital anatomy absolute the TreeView and a few controls acclimated to affectation bulge advice nd to execute searches for a specific node or group of nodes based upon a user supplied search term.

namespace EasyTreeView

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

            // start off by adding a base treeview node

            TreeNode mainNode = new TreeNode();

            mainNode.Name = "mainNode";

            mainNode.Text = "Main";

            this.treeView1.Nodes.Add(mainNode);

        }
