Ajax

Hi,


I have an .aspx page. In that i render 10 different reports using ajax update panel and Timer control. Now, i would like to capture content of a website on regular interval by specifying the URL(www.mysite.com/report.aspx). I am able to do this, but if my page has an ajax call i am unable to do that.

I tried the following:

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Threading;
using System.Windows.Forms;

class Program
{
    [STAThread]
    static void Main()
    {
        int width = 800;
        int height = 600;

        using (WebBrowser browser = new WebBrowser())
        {
            browser.Width = width;
            browser.Height = height;
            browser.ScrollBarsEnabled = true;

            // This will be called when the page finishes loading
            browser.DocumentCompleted += Program.OnDocumentCompleted;

            browser.
            browser.Navigate("www.google.com/");

            // This prevents the application from exiting until
            // Application.Exit is called
            Application.Run();
        }
    }

    static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        // Now that the page is loaded, save it to a bitmap
        WebBrowser browser = (WebBrowser)sender;

        using (Graphics graphics = browser.CreateGraphics())
        using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics))
        {
            Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height);
            browser.DrawToBitmap(bitmap, bounds);
            bitmap.Save("screenshot.bmp", ImageFormat.Bmp);
        }

        // Instruct the application to exit
        Application.Exit();
    }
}
