webBrowser control cannot find htmlElement after Ajax webpage update or in frame

Question

Using webBrowser control in a winForm. but when the webpage is updated by Ajax or in a frame, I cannot use webBrowser1.document.getElementById, etc. to find that htmlElement. The element also won't show in the View->Source code in IE.

The untimate purpose is to find that htmlElement and simulate a click or other function like invokeMember("staff").

Answer 1

The WebBrowser's Document object does indeed represent a live view of the DOM so there may be some other reason that you're unable to find it. DOM updates will not however be represented in View -> Source. You should use IE8's developer tools which will show you a live view of the DOM and maybe you'll see something like an incorrect/duplicate ID or something.
