Webbrowser Control and DocumentCompleted Event

Hi,

I've got a Webbrowser Control and would like to read out the content of a webpage loaded in this browser. The problem is that the page uses Ajax to load up some content - which happens after the page is downloaded, i.e. DownloadCompleted Event doesn't work. Is there a way of knowing when a XMLHTTPRequest has been initiated on the page and when the response has come back? Then I could just scrape that information?

I've asked many people about this problem and nobody could answer - so, it looks like it's a tricky one but hopefully someone can help here.

Thanks
