C# Newbie Question. Making button as a link, open in attached WebBrowser Form

Hello all.

I am making a small silly little basic one page web form while learning C# (Using VS 2005 Express).  I am stuck on how to link a button I have created, to actually send the user to a specified URL when clicked, into the attached WebBrowser form.
I thought
WebBrowser.Navigate ("http://www.google.com");
should do the trick, under each button, but they still do nothing.  What n00bish thing am I missing here?

Attached is my code:

#region Using directives

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Windows.Forms;

#endregion

namespace New
{
    partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }

        private void btnPrint_ContextClick(object sender, EventArgs e)
        {
           
        }

        private void progressBar1_Click(object sender, EventArgs e)
        {
       
        }

        private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
         
        }

        private void frmMain_Load(object sender, EventArgs e)
        {
       
        }

        private void btnPrint_ContextClick_1(object sender, EventArgs e)
        {
            webBrowser.Print();
        }

        private void btnXMFINFO_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate ("http://www.google.com");
        }
        private void btnEXEC_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnENGR_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnMETAPURCH_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnACCO_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnHUMA_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnSHIP_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnPLAS_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }
        private void btnSPEC_ContextClick(object sender, EventArgs e)
        {
            webBrowser.Navigate("http://www.google.com");
        }

        }
}



Notice I am using about 9 buttons I am wanting to attach to a different URL (buttons named btnINFOMARK, etc.).  I want these buttons to hold a URL, and when clicked, open the corresponding URL in the WebBrowser component that is on the same form.

Please help!  =)


Thanks,

Chris
