I am trying to use the WebBrowserDocumentCompletedEventHandler inside of a while loop but when the code executes the WebBrowserDocumentCompletedEventArgs is never reached.

Can somebody tell me what I am doing wrong?

int year = 1900;
int currentYear = 2014; 

private void button1_Click(object sender, EventArgs e)
{  
    while (year < currentYear)
    {
        WebBrowser wb = new WebBrowser();
        wb.Navigate("http://myurl.com/list/" + year.ToString());
        year++;
        wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wb_DocumentCompleted);
    }
}

void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    //Code is not reaching here
            MessageBox.Show("Test");
}
