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"); }
