Hello coders :-)

I have a little problem, but I don't know how to fix...

I made a webbrowser by my own cause I want to check some stuff when page is loaded. I do that with the "document complete" event. But after page is loaded the ajax can renew data, this changes should be recognized. I don't know how to make an event to the "html div" with content is changed.

I tried a lot of code from google search but I didn't found the code witch works :-)

Please help me :-)
so long phil

ps: framework 4.5, webbrowser seams to be ie11 if it's necessary :-)

What I have tried:

HTMLDocument doc = (HTMLDocument)webBrowser1.Document.DomDocument;
IHTMLElement2 div_result = (IHTMLElement2)doc.getElementById("inhalt");
HTMLElementEvents2_Event events = (HTMLElementEvents2_Event)div_result;
events.ondatasetchanged += new HTMLElementEvents2_ondatasetchangedEventHandler(UpdatedHandler);
