Beste helpmijers

ik heb even een vraag over treeview nodes selectere'n

Code: 
    private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
    {
        messagebox.show("test");
    }

werkt niet. Zowel niet via xml als normaal.

Even voor de duidelijkheid ik wil via xml een treeview wil maken waarna ik een node kan selecteren. Waarna er een speciale actie moet worden ondernomen. Laten we zeggen een console.writeline(''test") de code die er achter zit is in orde.

Code voor in lezen van de xml is ook goed

Code: 
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using System.Xml;
using System.Text;

namespace TreeViewSerialization
{
	/// <summary>
	/// Summary description for Form1.
	/// </summary>
	public class Form1 : System.Windows.Forms.Form
	{
		private System.Windows.Forms.TreeView treeView1;
		private System.Windows.Forms.Button btnLoad;
		private System.Windows.Forms.Button btnSave;
        private System.Windows.Forms.ImageList imageList1;
        private System.Windows.Forms.Button btnViewXml;
        private Button button1;
        private Button button2;
        private System.ComponentModel.IContainer components;

		public Form1()
		{
			//
			// Required for Windows Form Designer support
			//
			InitializeComponent();

			//
			// TODO: Add any constructor code after InitializeComponent call
			//
		}

		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			if( disposing )

					components.Dispose();
				}
			}
			base.Dispose( disposing );
		}

oplossing is

in de cs intialize

Code: 
 this.treeView1.AfterSelect += new System.Windows.Forms.TreeViewEventHandler(this.treeView1_AfterSelect_1);


in het form zelf

Code: 
private void treeView1_AfterSelect_1(object sender, TreeViewEventArgs e)
        {
            Console.Write(treeView1.SelectedNode.Text.ToString());
        }


code laat alleen in de debug zien welke node je geselecteerd heb.
